LT1 tuner in Charlotte NC area?
Seems like every shop in the area LS now and won't touch my ancient LT1. Sigma Six dyno in Concord tuned my old setup; but they aren't answering their phone or email; so it seems I'm SOL. I'd rather not drive 2 hours to RPM performance in Raleigh but if it comes down to it then so be it. Any suggestions?
