Nizpro modded turbo, 12pound actuatos. SMB 4" to 3.5" exhaust.Back when it was tuned the tuner told me no more boost could be put in because it would get valve float around the 380rwkw mark. So I'm wondering if I replaceed the valve springs How much more psi could I pump in? And what sorta power could I expect? And would my engine with stock internals handle it?Current tune 376rwkw 17psi peak.Thanks in advance for your input!

He has an FG and with your plenum they are virtually identical. Ray also runs 20psi with 400rwkw's and spiking to 23psi sometimes because of the 6speed auto.I run 19psi in my BA! that's why I need to pull my finger out and get this water meth kit fitted for up here.
