when did they raise the shift kit to 70? and when did their downpipes go back to 130?
dang it, now i'm gonna be really poor
question: can I advance timing with my mods plus PEM's and the above downpipe? i dont want to go to a 3.2 pulley just yet. maybe in the winter (then again more boost, but colder temps). Also, how much work goes into porting a supercharger? I might try it
