Tuning options
My 1999 M6 vert is still stock except for Borla cat back, bought LS6 intake and 1 7/8 headers with X pipe without cats to put on car.
The plan was to put on the parts and send the ECM to ECS for their $150.00 mail order tune, but read on someone else’s thread East Coast Supercharging stopped doing this.
Is there any other options similar to what ECS was offering?
Or should I just buy HP Tuners?
