SG...were you measurably faster using 2nd gear? Based on how our boost tapers off at high RPM's I found that I was actually slower on the infield if I chose 2nd for all corners except that hard right leading to the pit straight.

I have the TT and think it is great! It is not a piggyback at all but modifies the TMAP sensor signal to trick the stock ECU into adding boost. Unlike all of the piggyback solutions the TT requires no messing around with the stock wiring harness. Nothing needs to be disassembled. Unplug one sensor, and plug the TT in between the harness and the sensor. Voila!
