I see. I did not have my Pbox when I was NA, but on the runs that I have made the shifts are not as apparent as yours. Most of the runs I have done were using D5, but I can't believe S6 would make that much difference.

Max boost occures at max RPM, so I was thinking that his blower was hitting a sweet spot (around 8 psi) before he shifted causing the spikes on the graph. However, Drew has shown that the spikes were there even before the blower was installed.
