I just received my email tune from brooksspeed. Eric Brooks like Doug can write tunes for both SCT and Diablo. According to the butt dyno, this tune feels stronger than the 91 tq tune from Bamachips, which in itself is an awesome tune. With the brookspeed tune, I was actually able to chirp the tires shifting from 2nd to 3rd. I have not noticed a loss of power in the upper rpm ranges.
