This weekend I got a baseline dyno done too my truck it's a 04 2500hd lifted 5 inches on 35s. It made 288rwhp and 490rwtq hitting the speed limiter with a sb intake, intake horn, mbrp 3inch down pipe, 5 inch exhaust and a Ppe boost valve. No tuner on the truck. I don't think there bad numbers for having so little done and no tune.
