The EPA sued SCT so that’s why they won’t have anything to do with delete tunes.

If your truck is deleted and you return to stock you’re going to have a bad time. I don’t know about the 6.4s, but on the 6.7s with certain emissions codes they will enter an idle only mode.

If you haven’t deleted those custom tunes I wouldn’t. What are the names of the custom tunes on your tuner? Does it say something like Tow, Street or Race?

Did you get the pictures of the available custom tunes? There are four TQJE and four TQJF tunes. Tow, street, race, hotstreet. I attempted to use the TQJF street tune but the truck was stuck in reverse which told me it was the wrong file. The previous owner only ran a tow tune so I tried the TQJE tow tune and the truck was fine.

Thank you for responding by the way.

 

That’s perfect.

You said you just wanted a a little bit more power, so the TQJE Tow tune is what you’re looking for. Tow tunes are slightly more horsepower tunes that are safe to tow with, where as the more powerful Street and Race tunes will cause higher exhaust gas temps. It’s not that you can’t tow on a hot tune, it’s just that you damn well better being paying attention to your temps.

I have 4 tunes for my truck. It’s only ever been in the Tow tune.

 

Well my problem is or I guess my worry is on my only other diesel, 2010 6.4, I did the dpf and cat delete and did not want/need a tuner with all the bells and whistles considering I only wanted 100hp or less. So I found this and bought it. I've never driven a tuned diesel before that and this particular tuner you put in the OB port, run through the steps, and pull it off and just like that I had a 80hp tune. Immediately the truck was SUPER responsive. It was just plain incredible. I was so happy. Like a new truck. Unfortunately, shortly after that, the death wobble started and I sold it. Fast forward to now and I buy this one owner truck with this sct tuner and he even did the egr which I didn't before. So I was very excited. But after a few days I started to question if it even had a tune on it. It's no where near as snappy/ responsive as my last 6.4 with that 300$ 80hp tune.

Are these transmission tunes? It should be as responsive if not more then my old 80hp tune right?? Can I return it to stock using the sct and disconnect it and once it's back at stock, insert this Gear Boxz tuner and get the simple 80hp I had a few years ago?? I have no idea, but I know there is no where near a 80hp tune on it right now. I hope I am explaining everything right. Thats why I put my cell phone down on here. Feel free to call

It’s easier for me to work through it on here, but we’re starting to get out of my wheelhouse.

I can’t answer your questions about why the other tune felt better than the one you have now, it could be that whoever wrote the Tow tune you are on now simply removed the emissions from the tune and left everything else stock. I don’t know how that tuner does business. I also don’t know anything about the plug in type tuners like the Gear Boxz, so I’m probably not much else good to you. You might try one of the hotter tunes if you can get it to load, but I don’t know what needs monitoring, maybe one of the 6.4 will be able to help you out.

Don’t delete those custom tunes though. The EPA shut down pretty much anybody that was anybody here in the states and it would be a pain to replace them.

 

No worries and I am very appreciative of your assistance. I just can't believe sct told me to delete the custom tunes from my laptop and the original preloaded tunes would then populate and become available to use and now today a different sct employee tells me that won't work. If I was able last night to get my tuner connected to my laptop laptop I would have deleted the tunes last night. And I would have did exactly what the SCT guy told me yesterday And would have expected the truck to work perfectly fine with the original preloaded tunes because the professional tuner guy ( sct employee from yesterday) I honestly think he is doing the political correct thing to scare me?What do you think? How can it not work doing it that way? If i put all the emissions stuff back on, would the preloaded tunes thwn work? I was under the impression tunes were for deleted trucks only. That Gearbox unit clearly says dont do any delete unless you have a delete tune. I just don't know enough about tuners. Is there anyway to identify what HP is associated with the tunes I sent you? Again, it's been a pleasure talking and getting some information.

In closing brother, with all your diesel experience, what would your final advice be on what I should %100 not do to avoid screwing my truck up.

I’m glad you weren’t able to delete your tunes. I have actually had to do phone calls for tuning issues with SCT myself, but my experience was completely opposite of yours. I don’t know why he would tell you to do that. Emissions on tuning with no emissions equipment on the truck isn’t going to work. I can’t defend what he did, but SCT is lucky to still be in business. The EPA really cracked down a few years ago, so I can understand why they would be adverse to discussing delete tunes, lest it be a setup. But that doesn’t excuse him directing you you delete your tunes.

If you install all of the emissions equipment back on then you can absolutely use the canned tunes from SCT, but if you were to spend that time and money I would look for custom emissions on tuning. It is out there and people seem to be happy with it. Deleted trucks and emissions trucks both can be tuned, but the tunes don’t interchange.

I did a quick search and I found this from Rudy’s Diesel. https://rudysdiesel.com/files/v2/instructions/SCT-6-4-POWERSTROKE.pdf maybe this is the instructions for the tunes you have.

I have a 6.7, so I don’t know the tuner, but if you find the 6.4 area of the site you can probably search TQJE and you might be able to find more info.

I won’t tell you what to do, but if the truck has been running in the tow tune fine all this time, that’s probably where I would leave it. I know you’re sacrificing the performance of your other truck, but that’s probably the safest route. You can also continue to get more familiar with your tuner and tunes because the Livewire is a good tuner with good monitoring. You might get familiar enough to play with it more.

Also, at one time the consensus was not to update your tuner because it was uncertain how it would effect delete tunes, so don’t update it if you haven’t already.

 

That's awesome. Thank you. I notice there are 2 tows there though. I guess it's possible it's my setup. You are super knowledgeable by the way. What would happen if I walked outside now and used the tuner and returned it to stock? At that point, is it genuinely in a %100 stock state? Capable of getting married to another tuner? As long as I don't start it there should not be any issue doing that right? I'm sure you can tell how impressed I was with that 80 hp gearbox tuner. I was beyond impressed and happy. In my mind, logically, why cant i return to stock, turn the key off in the truck when complete, and then simply insert the gear box and go through its prompts and then be good to go. I cld then use the sct as a monitoring device only?? What are your thoughts on that since I'm not exactly sure what the current tunes are per say.

 

I noticed that after I sent it as well, so it must not be yours, but it does look similar. It could be a different package sold by the same tuner.

These forums are great for learning. It’s been a big help to me so I try to help if I can.

I don’t see any problem with that. Sometimes when trucks get sold the tuners don’t come with. Even in that case, you can over write the existing tune, it will just capture it as your “stock” tune. But by returning to stock you’ll be able to be sure the actual stock file is on the tuner you prefer. Did you unmarry the Gear Boxz from the truck you sold? I don’t know that it matters on that style of tuner, but it does on others.

 

I'm sort of in Old King Coal's boat as I have some limited knowledge on your platform both engine and Livewire, but the only thing I would make sure of is that if you use that Gearbox tuner to make sure it can handle the EGR delete. Again not familiar with that particular tuner so not sure what limitations it has. The other thing you could do is like mentioned before try the other tow tune, or possibly even the street tunes. Usually tow tunes add 50ish HP, and street tends to add 75ish. Those are ESTIMATES from other tuners that are possibly in the past. If you return it to stock you are correct in NOT starting it.

 

Thank you for the information but it's just so hard to believe that tuners these days are not coming preloaded with deleted tunes.. Granite I have been out of the diesel world for a few years but I can not think of any diesel owner who does not have a deleted truck and the few performance shops locally I called today Were hesitant to even talk to me about the deletes. I am basically at a loss for words. What if i can find a local shop who would write me a delete tune and/or Flash my truck or add it to my existing tuner that way I will know exactly what I am using. What costs are associated with tunes these days. Like I said, I am willing to bet my gun collection there is zero delete tune on my truck. Acceleration feels stock. No responsiveness whatsoever. I thought it wld equal the old gearbox 80 hp tune atleast.

 

If your truck operates then it has a delete tune on it, plain and simple. Your truck would literally not work if the emissions has been removed and NOT tuned. The EPA crackdown has made all of this very difficult. Since it is illegal to remove emissions stuff and they have been handing out $550k fines most places aren't willing to go out of business to delete your pickup on the off chance you are an undercover guy. The risk/reward is just not there.

All that being said it can still be done, it just takes secret handshakes and back room deals to get it done. This is why getting tuner names and recommendations, on this forum at least, has gone silent. Finding a local shop to do the delete and tune it is a great option but is hard to find at times. It sucks but that is the way it is now a days.

A little clarity on the updating the tuner front. IF you update it your custom tunes for the delete will still work and still be there but the canned tunes will no longer support deletes. So just don't update it.

Glad you clarified that. I assumed they didn’t have the right to go in and delete your personally owned tunes, but you never know now days.

@Daxton 1428 ; Local tuners are the way of the world now days but it might be tricky just cold calling them. Once you build a relationship with them with a few repairs and what not they maybe be more open to discussing it.

Here is a thread we had when SCT got its legs striped and why you can’t buy out of the box deletes anymore.

EPA Fines SCT/BullyDog

Only source so far. Usually when I find stuff like this it's already been covered on here somewhere. I looked around a bit a didn't see anything about it, but with the size of this place and all the subforums, it might be here, if so just delete it. I'd like to buy an SCT shirt or something...

Daxton 1428,
You aren't the only one who was shocked to come back to the diesel world to only find out that all I knew is no longer the same. I'd always been a Ram (Cummins) guy but it's the same for all of us as far as getting delete tunes. I had 3 hot rodded trucks prior to this that had tuners on them and 2 with deletes on them. But then due to health issues I'd dropped out of all this for about 8 years. Came back 2 years ago and it's been like WOW. And now I'm looking at a 2008 with DPF & EGR deletes but no tuner and it SUCKS.
