I Finnished up my charger install and I still have some work to do before i can get it tuned. I got a pulley from procharger(called them and asked them to send me the 11psi for the p600b) HOWEVER i have a feeling that they did not send me the correct pulley. Its a 2.67", I would just look at my boost guage but its not hooked up correctly right now so id rather not go out and smash on the gas and see if its the right amount of boost without a tune. Anyone have any info?

 

hook up your gauge and go check it out lol, we cant tell you from here

 

as i said. the car is untuned. I dont want to pay for a tune, then test it, find out i need a different pulley, then have to get it re-dialed in. What I'm looking for is anyone who knows a way to calculate the pulley size vs. stepup ratio to calculate flow to psi.

 

What size is the stocker and how much boost does the kit put out in stock trim?
