same turbo im running on my y8, pushes alot of cfm, i dont start to spool till 3100 - 3200 rpm, its too big to spool when not under load, so dont plan on sitting at a stop light reving up your engine and plaing on hearing your bov. I hit full boost at 5500 rpms and the hp increase is increadable per lb of boost, i would however recomend that if you use a 3" dp dont go any larger then 2.5" on the ic piping or the lag will be worse, btw you dont need the fuel rail or the fpr
