I agree, I wouldn't use it at all. The tuner should tune for your Octane in your area. If you can't get E or don't have the fuel system, you're stuck with what you have and just have to deal with it. I'd still chose a SC over an NA build especially if you have a build and you're pulling the heads off and doing a cam, dod delete etc, there is going to be more labor and plenty of room for error anytime you're digging into the motor. Simple bolt ons with a tune on E will get you into the mid to low 11s on full weight. Most blower setups will get you into the high tens on 93. Lots of options for sure.
