I know this probably a repeat question? working with a 03 lb7 with a zf6 first time this truck is tuned. did the normal injector replacement. went 20% now the truck is hitting 33 psi on street tune I built for it? now I am wondering if I need to pull back the tune some more. Setuping a day to hit the dyno this week. truck has exhaust downpipe and intake horn and ppe boost valve. I was running my mechanical boost gauge on truck
