|... does that really prove that I don't have an air leak significant enough to hurt performance?
Here's an old link showing my vacuum test results again.
I can't seem to figure out why I'm loosing power at lower rpms (or at high power, who knows?). The power band is not continuous --no spikes or dips-- going from idle to max power. Shouldn't power be rather continuous from idle up to WOT? The only thing outstanding right now is the CAS.
Thanks for the comprehensive vacuum link.
(Another link documenting that even a new EGR valve leaks some amount)
