Well i finally got my truck on the rollers a couple weeks back and was kinda dissappointed.. with the mods in my sig the Truck made 451 consistently over 3 pulls.. boost was only about 26psi... im used to seeing over 30+ on that same tune... granted it was on an unloaded dyno... hopefully i can get closer to 500 on a loaded dyno.. what other mods should i do to get to 550-600hp range
