diablo 91 tune Corvette C6

Post by Randy_LS2 »

I have 2 simple questions. I have the Diablo 91 tune, I know my car can run on 87 gas in emergency situations, can I run 87 with this tune as well? And how about the 02 sensors, are they deactivated in this tune or not?

no you can not.. the timing is advanced.. should never run 87 in that car anyway.. but if you do, you would want to restore the original backup stock tune to the car first..

rear 02 codes, cat codes, etc are not disabled.. you would need to get a custom tune done for that..

Thanks, but I just read on some topic that the timing on the 06-07 LS2 and LS7 is not advanced in the 91 tunes...is that true?

The WOT timing is changed in the 91 tune?

some specific 91 tunes use stock timing levels, yes.

Just want to be sure my engine/tranny lasts like it does on the stock tune :oops: not that it can run too lean or wrong timing or something....

I have a complete z06 exhaust installed and a friend of mine says the diablo tunes are running too lean for my mods ( vararam intake and z06 exhaust) is this true???

No...the exahust has no bearing onthe AFR, the CAI leans out at speed but the airflow is measured by the MAF and compensated for.
