Got boost to sit at 15psi using the overboost valve on a softer setting.This will do until I fit the new injectors, valve springs and get a tune.

Plenty of time of Dyno time spent on this car overall.Shows some love has gone into it.Appears to be a nice tune. Do you have AFRs/Lambda

I don't know all the technical stuff too much...what are AFR's,oh and while I'm asking I see WOT thrown around, what is that. Thanks. I'll upload a PIC of the turbo.
