So, finally got a boost gauge and installed it this afternoon. Did a few runs this evening. As usual, first and second feel very strong at WOT. Saw ~11ish psi in first, about 13 in second. Third made about 13 as well at WOT, though it didn't feel as strong. There is no bucking in third at WOT. There is, however, considerable bucking/hesitation in second and third at partial throttle above about 3k rpms. The boost isn't jumping all over the place though. I guess that this hesitation at partial throttle is the next thing I need to address. Any ideas?
