I'm about to purchase my lap3 ecu. Undecided on which tune.
My mod list is basically all bolt ones including wmi.
I will be mainly running e30-e40 (wmi when needed) mix will that be enough for 2.5 tune?
My main concern is if I take my car on a road trip to pick up daughter from college and wanted to run 91 would that cause any issues if I wot it a few times?
Hi Paul, If you plan on running 93+E85 mix+WMI, Stage2.5 ECU's max potential will be reached. If your base fuel is 91, adding E85+WMI, we suggest Stage2. Going wide open throttle with the octane fuel lower than the requirement, then you may experience knock & misfire. So it is important to make sure you have the required fuel for the tune. If you stay out of heavy throttle/boosting, it is fine until you get the fuel you need.
