Twin 61mm turbos. Boost was about 13-15psi, it would spike to 15 and then stay at 13, 16 degree timing 91 octane and A/F 11.7. Put down 690/614. Tq was a little on the low side but who cares. The thing is hard to keep straight going down the road. Greg at RET did the tune. http://www.youtube.com/watch?v=tBgzLe-pAZg will post the graph once Greg emails it to me
