So guys just had my Stage II Pro-charger installed today, everything sounds great and looks great but i don't know if maybe i was expecting a whole lot out of the box or if i have an issue? I don't feel like i gained much, maybe i'm not use to centrifugal but it feels like it pulls just as it did just with a whine/whistle now. Second, It feels like when i punch it (not even WOT) it "sputters" or "lags" (sorry I cant find the proper term) to get going, sorta like when its cold in the morning and it doesn't feel so right till it warms up, that issue. I'm sure 90% problem (worries) could be me and also need a tuner to get a hold of it. All im currently running on the car right now is a lethal resonator delete and a roush catback. This is not a post to bag procharger or anything of the sort! Was a GREAT put together kit and awesome customer service with any issue (which was bare non) So please any advice or help be great guys/gals. Be easy on me haha im not new to mustangs but new to Centrifugal.
