The reason i ask is because i want to make the most hp and i have seen a guy dyno with the stage3 on a turbo and made 408 to the wheels.......The most i got out of my last motor was 369hp on pump gas 93 oct with the stage 2 crower......and I am not worried about the cost but the bisimoto cams (everyone show 20hp more on the dyno with these cams) for the price i just scratch my head at and say I could go buy some 40hp pills for the nitrous system i already have and it would be a little cheaper...... I am open to any and all suggestions and yes i have googled it time and time again and everyone gives different opinions. I am WANTING TO BUY THIS TO DAY!!! Christmas present for myself so the sooner the better on the responses.
