Just got back from the shop. Glad I paid them to install the exhaust. Beat sitting on my snow covered driveway! The stock exhaust must have weighed 250lbs with all the emmission crap. First impression was very impressed. No droning. The motor is still quiet but the turbo is very impressive. At idle its very docile. Hit the gas and its a beast! All three tunes are nuts, although I plan on keeping it on the mild setting. I love the fact that you can adjust for tire size as well, as Im running 37" tires. The pro flo exhaust had to be cut and welded. Fit was not the best so Im glad I had a shop do it. Only cost me $225 for everything installed so I'd gladly pay that again. MPG is already going up. Will update on that.
Awesome man! I thought they could only adjust up to 35" tires?? Have you noticed better shifting with the truck adjusted correctly for the tires? I have 35.5" tires and my shifting seems really messed up
Well I didn't try to adjust the tire size till just now. Manual says adjusts up to 39", but the mini maxx only goes to 34". Kinda pissed me off, but maybe Im doin something wrong. I'll call tech Monday. Still runs great though.
So the final answer is 34"?? Thats dissapointing, I had heard 35" and figured that would be close enough to my tires. I do know that 08-10 trucks the dealer could adjust to pretty much any tire size and the 11's are limited to the stock tire size options. I wonder if that has some thing to do with the H&S tuning. I hope they have it figured out in a month when Im pulling the trigger
Tire size capabilities have nothing to do with our tuning, it is merely the limits of the ECM's internal programming. The 2008-2010 had much more room to play with, whereas the new 2011 ECM's do not. We are in the process of finding a work around, and are confident we can do so, but for now 35" is the biggest size we can adjust it to.
BTW...tranny shifts much nicer then stock. Stock was always wishy washy, never knowing which gear to go in at lower half throttle speeds. Now its very crisp and firm no matter how much throttle.
I haven't noticed any difference in my tranny shifting since H&S hasn't done any tranny tunning in their tuner for our truck yet. They are still working on that also
I believe if memory serves, its 34". I have the muffler with dpf delete. What started good, is goin down hill. Tonight I got a C.E.L. and ran the diagnostic check with engine off, like it states, and the mini maxx doesn't even pick it up. Lovely.
Updating the tuner should fix the issue with your tuner not reading your CEL. There are numerous DTC routines, and we had to update the tuner to pick them all up. We have not had any issues since the update. Let us know if you have any issues with the new version, and we apologize for the inconvenience.
I have installed 20 or so of these kits on all makes and models and have had great luck with fit...no welding at all. Where did they have to cut and weld? Should have clamps for all joints...just in case you have to return to stock
Nothing was cut or welded on the stock exhaust. That all came off fine. The pro flo must have been meant for a long bed because it was too long so it had to be cut down.
As far as the map sensor, where is that? I have the most recent software. Thanks.
Great to hear, and thank you for following up and letting us know the issue is resolved. Anything else you need please feel free to let us know and we will take care of it!
Could you tell us what kind of mileage you are seeing? I have the same lift and tires and am debating adding the programmer and exhaust but want to know if the mileage increased at all first.
Just did the mini max tuner with the magna flo stainless exhaust, UNBELIEVABLE! It sounds like a jet engine, $916 for the MINI and $575 for the exhaust, easy install w/the muffler. I blew a dodge w/bully dog away today, 3 truck lengths at 85 MPH! Don't hesitate, DITCH the DPF, what a difference@
I have no doubt about the power. I am really curious about the mileage though. Per the dash (which I know isn't accurate just using it as a base line) I get 14-15 doing 60mph or 10-11 mpg at 75-80. Keeping in mind I'm on 37" tires so I'm going a bit faster. I hand calculated the other day and while the dash said 13.5 mpg I actually got like 12mpg.
I'm so on the fence about pulling the trigger on the Maxx and FloPro 5" (no muffler) delete. I'm just worried about the warranty (i'll have to get over that) and that Maryland is supposedly starting emissions on diesels in 2013. I guess it's reversible, but I'm not sure how much I'll enjoy swapping it every 2 years...
all depends if they want to put the diesels on the rollers, they should just do a obd2 check. thats why i haven't got a new truck my 04 has no emissions, but it's getting tempting
I guess it is safe to say that there is a noticeable difference in power with the DEF delete with muffler? Common sense would say yes if you have seen the exhaust. LOL
The difference in power is amazing!!! Makes me love my truck even more, also like stated above the H&S customer service is unreal. Couldnt be happier with my decision.
Toyo, I run on performance all the time. DO NOT tow on performance scale back to the tow or stock tune. Someone recently put up a thread that they blew a turbo pipe while towing with performance tune. Its way to much pressure for a load.
