So I'm stuck right now with my injectors me and jesse have been messaging back and forth talking about my options. Heres the deal I'm for sure putting in 190's on my truck from him no doubt but with the amount that I tow and as periodically as I do I don't know whether to go with a 75 nozzle or a 30 nozzle jess said that he runs a 190/30 on his tow rig and its clean and great but if i want to run a 75 on them as long as my tow tune can restrict the fuel well enough it wouldnt hurt it at all. What are my risk if i go 190/75 i tow anywhere from 16 to 32ft cattle trailers full of cows and or horses and also farm machinery pretty often. Also what are my hp differences between getting the 190/75 vs the 190/30 need help and suggestions and experiences?!?!?

I don't think that would be a bad move OP. I'm running 175/stock injectors right now and it is very quick. I installed a BTS stg 3 turbo and it cleans those injectors up to no smoke at all. I will be continuing to add supporting mods to see what potential these can make with live tunes. This way I can sort of have the best of both worlds. A high HP truck that can load a tow tune and pull full weight. Also, add a ported intake manifold to your to do list. This will help with turbo spool and will aid in lowering EGT's.

Odawg made 618 hp and 1000tq with 175/75s.

Most people who are big into towing don't go with 190s. That is just too much fuel and it will be smokey, or you will have to pull a ton of fuel to even make it possible to tow something that heavy. 190s will haul butt!!! But not a lot of weight, unless you can clean them up with a larger turbo charger and more air flow. Although to a certain extent once you get so big on the turbocharger you will have more lag and it will be easier to get under the turbo and it will make towing and egts even worse.

Also what do you have done to the truck so far?
Head studs?
Bulletproff?
Any updates?
Oil cooler?
EGR?
Tranny?

Maybe I can ask this question. Why 190s? Is it for racing and/or dyno... or are you under the impression that it will tow more?

I don't have a tow queen but I heavy followed many people on this forum and bigger is not always better unless you have LOTS OF MONEY!!!

155/30 and a stage 1 turbo has proven to be a great tow combo. You can actually floor it up hill on a good tune. With 190s you will have to be constantly watching your egts, pulling fuel from the tune, and with a big turbo that can actually clean up your 190s you will lug the motor and fall under the turbo and also have much more turbo lag. No reason to get a giant injector that will just have a ton of fuel pulled on it... Unless you are looking for a major dual purpose truck??? Or if you have a ton of money!

IMO 190/30s, compound turbos, head studded and complete bullet proof, ported intake, ported heads, aftermarket air intake, complete fuel system, regulated return, water/meth injection, a fresh hpop (needs to be in good condition), a built tranny etc.. etc.. This would be one mean towing machine

Or you could just do 155/30 and a stage 1 and have almost the same towing ability

Truck has arp studs a fuel return and fuel system are about to go on waiting to come in egr deleted banks intercooler and elbow intake pipe also air flow system and 6.4 banjos

Not bad at all so if I was to run a 175/30 you think i would still be able to tow full weight and have the hp best of both? As long as I beefed up the turbo and ported the intake manifold?

For towing your kind of weight the Stage1 with 155/30's is a proven combination however the Powermax with a billet wheel and 175/30's would be a workable combo as well. Don't go bigger than you can use because pulling fuel from a big injector to keep egt's and smoke down will result in less torque than a smaller injector that you can run a longer pulse width on. Bigger isn't always better.

Thats a great start... more than i have!

Are you making a dual purpose race/tow truck or a tow queen?

Would the 175/30 be as good as the 155/30 as long as the turbo matches up well enough?

A tow queen pretty much haha I don't really need all that racing business just enough to have fun with on the down time.

^^ If thats the case then I would definitly stick with 155/30s or 175/30s. You will be able to tow to full capacity with a good tow tune and will be able to have some fun around town with a race tune. 190s won't work in this situation.

Haha well that's exactly what I needed to know the 175/30s are looking to be what it's gunna be now I just need a turbo that's compatible with it for the loads I pull ideas anyone?

To really clean up a race tune on 175/30 you would need a pretty big turbo IMO. Like a stage 3 (68mm). This all depends on your supporting mods because 175s require a lot of air flow ported intake, water/met, etc will also help. Now with a big turbo you will have more turbo lag which is not ideal for towing (it can lug the motor while cruising, cause high egts, take forever to spool). Many have run the 175s and a stage 1 on a race tune but they could hit 1800s on the egts which gets really high really fast.

The original stage 2 from MTW is no longer available, there are other stage 2s out on the market but they are relatively new and I don't have much personal knowledge on them but I am sure some people will chime in. Also the hybrid might end up being discontinued

155/30 would pair really well with a stage 1 from Mad Turbo Werks. Many have reported this combo to be a towing monster... jetjock15 has this setup and he has reported that it does great!

6.0 - Stage 1

Now these are just my opinions about turbo setups for racing purposes... for towing it is a little different... but this should give you an idea of how they turbos pair with injectors on race tunes with regards to actually cleaning up the smoke/injectors. Now any turbo can run with any injector but it might get laggy if the turbo is too big and smokey if the turbo is too small.

stock injectors = stage 1 or powermax 63.5

155/stock = stage 1 63.5mm is slightly too small but stage2/hybrid 64.7 is a little too big???

155/30 = hybrid/stage 2

175/stock = stage 3 68mm is slightly too big but stage2/hybrid 64.7 is a little too small???

175/30 = stage 3 68mm

I pull 15000 lb ( 41 ft toy hauler ) flat ground w/ 155/stock & powermax billet wheel on Eric's heavy tow tune steady 1000-1200 egts!! I wouldn't want any bigger injectors on my set up !!

I've pulled right at 20000 with my hybrids and non vgt turbo just fine. It's all about tuning.

I towed 13,000 pounds on a regular basis with my 190/75's and PowerMax. EGT's were manageable, as long as you didn't floor it up a hill. Using tow/haul helps as well, because it will downshift earlier and lower EGT's.

I think 190/30's and a billet 68mm PowerMax or a MTW Stage 3 turbo would be awesome.

say i go with a 155/30 with the stage 1 turbo for this tow monster i hear yall talking about will i still be able to have some fun when im not towing what will be the difference between these and a Powermax with a billet wheel and 175/30's?

I have 175/30's and a Hybrid... Having slight towing issues with heat! Drives great when empty though.

I dynoed 590 and 603 HP on Saturday but realistically I am probably at like 520 more likely!

I don't think you will be losing much with the 155 and stage 1 turbo compared to my setup.. you might be saving yourself from a fuel system, ported intake, and a TRANSMISSION if you go with 155's....

These 175's like to eat trannies LOL.

Also it depends on your tire size... on stock tires I believe my setup would be fine.. But with 35's I think it puts my gear ratio JUST under the turbo. (The Hybrid spools after 2k RPMS on my truck.

Oh haha well thats good to know maybe i ought to be more open minded about these 155's then!

I'm still interested in this 175/30 and a powermax with a billet wheel combo anyone know anything about this set up and how well it would work?:look:

This is what I would recommend. It should be a very fun combo for you and allow you to tow. Again it's all going to come down to tuning, but this should be fun for sure.

Do you see any problems i might run into with this combo though it sounds pretty promising just worried about my egt's getting to high?
