I don't know, I have an EVO 1. What does it say it's for? When all else fails read the directions.
I can't see how it is going to make your gauge read correct. The basis of the MAP FOOLER is to fool the computer into thinking it's getting lower than actual boost as to not defuel your engine, right? That being the case, your EVO 2 is reading the false readings from the computer AFTER the MAP FOOLER fools the MAP sensor, the MAP sensor sends the false data to the computer, and the computer sends it to your digital gauge.
I don't see a way around it.
