Sorry about the slow response,
I was only running 8psi when I put the car away. I will be installing a new headgasket when I pull the car out, then I'll be running around 14-15psi. As far a s sppol time, @ 8psi spool is fast, I'd have to try and find some datalogs on my other computer to tell you for sure, but at this low boost level it feels like any time I got WOT I'm basically seeing full boost. Obviously running a higher boost this would be slower.
I haven't dynoed at this low boost level, ultimatly my goal is about 400whp.
