The best way to find out if your gas is good enough quality to run the tune is to data log it, buy a map pack that suits your mods. Then data log the lowest octane rating first, look for knock and of course afrs and other variables, then move your way up in terms of octane. But first look to see how the stock tune is doing.

The best option is to use a custom tune, you can't always rely on ots maps to perfectly suit your car....
