When 526 is not Enough

is the 93 tune that comes with it meant to be for a stock car?
I couldn't catch a c7 z51 last time on the straight, thinking about getting the tune, 30whp will for sure help.

I have the 93 tune on a stock car. I did not do a before or after dyno run and will not worry about it until I add headers and CAI shortly. That said, the 93 tune improves overall driveability from idle to redline, with the car really waking up in the 3000~5000rpm range. Based on current street driving and my last track event, I have no reason to doubt their numbers. In fact, I ran 100 octane at the track and the car ran even better, as others have noted.

Livernois included a 91 tune, 93 tune and a stock tune. Flashing is easy and in five minutes you can be back to the stock tune. The tuners in my area have not worked with the GT350s yet, and all recommended Livernois until they have time to properly test and tune this car. I think it was money well spent and I would do it again.

No, I like keeping things simple at the track and on the street. It is much easier for me to stay with the 93 tune and use race fuel (100) on track days, which using the non-scientific butt dyno, was noticeable coming out the corners. I know the FT tune would develop more power, but am not convinced the tunes nor car in general is setup properly at this time.

I see your point. I figured I'd take a chance on the flex fuel since I'm otherwise stuck with 91 and I doubt there is much safe power to be gained trying to tune for that. I'm happy with the results.
