Umm, no he won't. His car makes great power on pump gas and I'm pretty sure he already has a map in his AEM for race gas.
It's funny how so many people talk shit about stuff they don't know jack about. In the end, it just makes you look like the ignorant one running off at the mouth.
You can have 100+ different fuel maps stored on your laptop for the AEM EMS. I have a map for 93, methanol + 93, and C16. Point is, I could have 40 more maps if I wish for various fuels, or combinations of fuel, or types of injection(nitrous, water, methanol, alcohol, etc...).
I have no clue what is done to Matt's car, but knowing Matt its probably pretty badass.
