i would make sure all the intake pipes and filter is on tight and everyhting and that there are no holes in them and make sure you have the BOV venting into the intake. and the stock "boost gauge" doesen't go all the way up, at least i havent' seen it anyway. i get the stumbling feeling somtimes to when i mash on the gas but i can let up off and it does fine. anyone know what that might be?
