For those who are interested, I have finally finished the LPE Stage 1 Package install on my WS6. It only took the whole summer to get all the right crap and finally get around to installing it, but so far it seems like it was worth it.
The Performance package consists of a 90mm high flow intake and throttle body, Corsa stainless steel exhaust, and custom ground cam. The company claims I should see 420hp at the crank. I have no idea if that's what i'm getting, because the car still needs some fine tuning, and after spending all the money on the parts, I have none left for a dyno run. But that's ok, the pants-o-meter will do for now.
The hardware:
