I know I am still working on my DIY mods and aftermarket bolt ons, but each day is closer to getting one of the ECU tunes than the day before
Here is my Q for all of you not just AA and OE.
If I can get 98 or even 102 octane fuel, will the ECU tune take the advantage? If so how much more gain can I expect?
Getting 98 fuel is not cheap, I just want to know if it will be worth the effort and cost. I am using 91 now just for reference.
