I have been working the past few weeks on coming up with a tune for my V6 Roadster and I am getting close. Thus far, I have been able to reduce the rev hang in lower gears while smoothing out the torque band further up to redline. The engine sounds better (clearly a very subjective thing) and it pulls better into higher revs. At this point, we are trying to work out how aggressive we move the timing to keep the knock sensor in line. I am hoping to come up with at least two tunes depending on what octane gas in use. A few questions:

Has anyone else done a non-factory tune for their roadster? If yes, were you able to get rid of all the rev hang in lower gears? Also, have there been any cooling issues running the tune more aggressive with higher octane fuel?

Hoping to have a final tune in place by end of the week which everyone can then use at least as a baseline for their own car. More details to follow?

OK Guys this is good info. I will learn to drive around it rather than chase a cure. I do like to rev match on downshifts so that will be a challenge. It is a fabulous car. You cannot be shy with this vehicle. I get approached every time I drive it.
