Hey all! I just completed my c5s6 6 speed swap.. Its awesome! BUT, im finding the oem euro manual file to be a bit flat for my liking. Previous, with the auto, the car was MTM ecu tuned. It was quite a bit snappier. They wont update my file though. I want the tune back but for the manual. Does any tune these belt v8s anymore? seems to be hitting road blocks on all avenues.

See if you can get ahold of Breakout Motorsports in NY. I have had good luck with Brandon in the past, although I'm not sure he is still in the business.
