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.
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.
My thoughts on the 75% nozzles was if he's gonna pay for the upgraded nozzles, he may as well get as much out of it as possible for the cost.
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.
