I have a 2006 C6 Corvette with a manual transmission. I was wondering exactly what the difference is between the perfomance stock tune and the Diablo Tune. I was also wondering what the diablo does to this car to make it faster. It seems to me that it just runs a little leaner and that is about it. I was hoping for a more noticible difference since you advertise a 25hp increase to the rear wheels.

Thats basically all we did with the C6 tuning, it did not like ANY additional timing, so we ended up leaning it out a little. This produced about 10-15 hp gain at the rear wheels. GM did a good job on the stock calibration on the C6's. I also recommend using good quality fuel as during testing we used different brands and some brands 93 octane produced up to a 5 deg knock retard count which resulted in a loss of 20 hp at the wheels.
