I will double check on the Boost # but I assumed it was manifold pressure.
6500 RPM was the best it would do on the dyno pulls.
The headers were blue before the dyno runs. There didn't seem to be any change in color during the dyno session.
Heading to the track today. Wondering whether to shift on time or RPM??
