    Exclamation Has anyone looked at Rivas tunes for the XXX charger?

    I am in the process of making a break-in tune for my new setup using the Maptuner. I downloaded both of the 142 tunes. The open class 142 which says it requires "AV gas" and the normal 142(XXX) tune that does not. Can someone explain to me why 1. The open class that requires race gas has 3* of timing up top less than the tune that does NOT require race gas? And 2. how the hell does the XXX/142 use the same fueling as the XX/135 tune? It is fcking scary to think people are just loading these in and going....

    Try the stage 4 9200 vt1100 riva tune, that's the base one I started with aside from it being alittle lean out of the can. It's a great tune with the 142 wheel.

    It's more than a little. My 135 tune was 28% lean to get to 12.0. This has the same fueling as the 135 tune. The stage 4 tune has too much timing whereas the "race gas" tune has less...

    We will see how it goes. Shouldn't be too bad to dial in. I already have a good base with the 135 wheel, so I just added to it to start.
