What do you guys use to lower the boost for stock motors? How much boost will it make once you lower the boost? I know I'll need colder plugs and GT500 fuel kit.

Either steeda underdrive pulleys installed with the kit or a 3.47" pulley from Carmen Goudy. The steeda's will get you around 9 psi boost and 440 RWHP. The Carmen 3.47" will get you around 11 psi and about 480 RWHP easily. Or you can run a V10 water pump pulley and 90mm idler leaving the stock blower pulley on and using your factory balancer pulley instead of the one that comes in the TVS kit and make around 13 psi and 500+ RWHP!
These are the options we have tested. I really recommend the GT500 fuel system and spark plugs. Let me know how much power you want to make and ill get you a package deal!
