Much thanks to Charlie @ RPM Motors for spending so much time dialing in the tune. Car was tuned in SD, the MAF is there to help make passing smog a bit easier (will enable MAF for smog test and adjust tune at that time). LS6 injectors that were flow tested/cleaned/blueprinted--think they are around 30s at 87% duty cycle.

Car put down 460/423, up 23hp/25tq from the old numbers (437/398). Dynomite Dyno as well. I've only driven it briefly, but pulls a lot harder and is noticeably louder. The gas pedal is hard to push, don't know if it's just stiff being the throttle body is new or that is normal, but slow speeds have had some bucking just because Im not used to it. Finally done with the power mods, onto getting it to hook/handle/brake better.
