i know those are insane, but whipple is the only thing close to that kit, and whipple sucks. its not intercooled, it has a piggyback PCM module that i have found is a lousy one, it has two injectors just stuck right before the throttle body, so when your not WOT it puddles up and detonation occurs..... the list goes on about whipple. and they have a garunteed 30k mile block breaker
why not do the magna charger? we put a few on here in colorado and they rail. we even did one on a stock 6.0l and that thing had a ton of torque as well as good mid-high range. magna chargers are pretty much the only ones i have delt with and they have all been outstanding. we did a couple on new vettes too, and they were mean as hell.
