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.
All good bud, I think you had a fair observation! It's really just DCT FTW.
IMHO it's like adding 50whp, lol, along the same lines as the PDK on the 911.
