Wanting to get bigger nozzles in my built trans lbz. Stock cp3 stock turbo, my question is will bigger nozzles help hold rail pressure on a stock cp3 or make it worse? My thinking is a stock injector at 3200Pw in my mind would require more fuel then a 30% over nozzle at say 2600pw? Hoping to upgrade to Danville’s 68stg2R sometime but that will be down the road a bit. My stock cp3 does sometimes have trouble holding rail on my max effort built trans tune. I’ve seen it dip to 23 a few times usually hangs around 2k lower then commanded at WOT

Bigger nozzles won't help your cp3 hold rail pressure. What they do is cut your PW down so your using the fuel where you need it and not chasing the piston with fuel. My first lb7 I put 30 over nozzles in and picked up .3 at the track. I probably would go right to a 60 over if your going to spend the money
