Here's the final results of my turbonetics kit. T-60 turbo, HKS 2mm headgasket, 550cc injectors, Greddy Ultimate, walbro fuel pump with regulator and fuel return line (and my gaz gauge is working fine), R154 tranny with 3" aluminium driveshaft. This is the final tuning @ 17PSI.

430whp & 415wtq @ 17PSI.
416whp @ 16 PSI
400whp @ 15PSI

Here's the video link :

What are the specs on your exhaust from the midpipe back? Sounds 3" but much quieter; the sound that took me four trial and error setups. ;)
