race fuel Questions
#35
Leaded fuel will foul your o2 sensors rather quickly and your cats if you have them.

Be careful not to run 100% meth with the AEM kit to often. Not sure if the pump is set up for it.
#39
You have to do the research yourself but I heard that not all pumps are rated to run 100% methanol. You could burn the pump. Just trying to help.

You should talk to Evoms. My guess is that you won't be able to take full advantage of race gas because your boost will be limited by the 91 tune.

Evoms used to use GIAC as their ECU tune and that required the hand held switcher to switch between pump and race gas files. They now have their own in house tune (EVOMSit). This does not require a manual switcher. It automatically switches files based on fuel grade in the car. You only need to add the race gas.. You will difinitely feel the difference. It's night and day.
