91 octane tune

Post by dyogi »

I took the '07 Vette out for a first ride since installing the Diablo 91 octane tune. The car seemed to run more responsive and shifting seemed to be better but the car idled a bit rough, almost as if it had a miss. Is this normal? The car is completely stock.

The software version on my tuner is 8R10. Does it need to be upgraded?

Thanks,

Dennis
