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?!?!?

Having the right turbo to help clean up the fuel is essential and aids with not having to pull as much fuel. If you can clean that fuel up you'll be golden. As for the /30 vs /75 nozzle, I think you could have fuel pulled and have your tuner work you a pretty good tow file and I'd recommend Matt at Gearhead for that. tow tuning also works the transmission data and he's great at it. I say go with the 75's and be done with it. I'm assuming you're upgrading turbos because 190's on a stock turbo is pushing the envelope a bit...hahaha It's doable but not optimal.

Thank you I was thinking it should be fine as long as my tune was good also just got me thinking when he told me he ran 30's on his but ok Jesse has me tune that he said would work good with the 75's and yes I'm definitely switching out turbos I was thinking a stage 1 powermax do you think that would be pretty idea or you got any suggestions?

stage 1 is a great turbo. It won't clean up 190 completely but it's a great towing turbo as well. You can also opt for the 10-blade turbine version which will help flow more air on the top end which will aid in cleaning up the fuel but has the potential to be a little laggy down low, but that can be fixed with tuning as well.

I think you will be better off with 30 nozzles, there's not going to be that big of a difference in HP from 30 to 75s maybe 15hp tops and thats with a race tune, not a tow tune. 30s will atomize better and give you more torque since you are using your truck to tow mainly. 190s are pretty big for a pmax or stage 1 so keeping egts in check will take a lot of tuning.

I running 190/75's with the hybrid. Truck towed roughly 6k lbs from NY to NC through the hilly terrain of WV and Virginia with only hitting about 1000* egts running ID's tow tune with breaking. I know its not a lot of weight but the stage 1 will flow better than this hybrid. I say go with 75% nozzles.

If you're towing frequently, then I'm not sure why you are looking at 190cc injectors and a dinky turbo like a Stage 1/Powermax. I guess it all depends on the weight you're looking to yank around. I have 190/100s, and I couldn't imagine trying to tow with these injectors and a Stage 1. On Eric's Xtreme X, I could 1800F EGTs before 80 mph empty and I don't see the point in getting 190s and then cramping down the injector's ability to flow just to say you have 190s. I guess, what I would recommend is if you go with 190s, then get at least 50% nozzles as 30% nozzles (like stock) are going to be too small.

I've been curious about 190s for a while so I'm glad the OP started this thread. Is it possible to keep the 190's cool enough to tow? I've always thought no?
 
#13 ·
I have several friends with them that tow there weight isn't that high maybe a two horse trailer plus the horses and they don't have any trouble that's about 6klbs right there easy (if your like me I tow about three or four times that). From my understanding it's all about your tune and turbo.

^^ I've got TSD here pretty close for some Live tunes and my turbo is big enough to handle 190's so I guess I should be good.

Guys it sounds to me like the OP is towing well in excess of 10,000 lbs several times a week. I personally don't know why he would be considering 190's with any nozzle for a truck that does this. I know he wants a truck that plays too, but I think that's demanding a lot. It's doable, but not as easy as slapping on a powermax and having a tune emailed to you.

OP, if you HAVE to have 190's go with the smaller nozzle. If it was me I'd stay down around 155's, maybe stretch it to 175's with a small nozzle. IMHO no need for more than that with a small single VGT towing as much as you do. I would also recommend live tuning.

Would I be safe to run the 190s with a stage 2 turbo, fuel return and fuel system, arp studs, and a new inter cooler and still tow? I thought with all this I would be fine but y'all are throwing some pretty good advise at me and I need to know I'm considering bumping down to a 175 now with a 50 or 30 nozzle

Isn't it the nozzle size that really dictates the driveability of the injector? If so why not go 190/30. A 175/30 and 190/30 can be made to run the same with a tow tune and when he's not towing he has more than the 175/30. I agree you would probably want a larger turbo though. I'm really interested in this thread cause I've always thought the 190/30 would be a good injector size for the fact that is has a smaller nozzle for towing but still large enough to have a lot of fun with. I'm interested in what the op decides to go with.

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.

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.

^^ 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.

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 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.

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.

OP, remember this, if you add more fuel and you don't add more air, you're gonna have a ton of heat. Having more air to help clean that fuel up will aid in keeping egt's at bay. FWIW, it may behoove you to consider a ported intake manifold. You can pick one of those up cheaper than a set of injectors with nozzles.
