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 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.
A bigger turbo is going to increase your cruising egt's...
No it wont. I went from a hybrid to a 68mm vgt. Cruising temps stayed the same. Even when I went from a 64mm non vgt to the hybrid then to the 68mm vgt...cruising temps at 65-70mph were exactly the same.
Not many miles on this turbo yet....less than 100 before I drove it to Warren Diesel to have some work done. So maybe 200 miles. Tuning needs adjusted big time. Tried TSD's SPD and shift points need fixing big time. Running 190/75's.
While my truck is down at Warren's I'm gonna have Jesse write a street tune for it.
