Ron Smith at RS Motors tuned mine acouple years ago. Crossed it over to E85 and cleaned up the tune on the fucked up alpha map the car was on from the original build. Picked up acouple hundred horse (boost). Then Carl at Lancer service is huge on GM but getting into AEM, I really like Carl. But I had my car at Nth moto earlier this year and they put the new infinity in and diagnosed the car that is on its way back together so I can get it back there.
