If it is running any boost at all from the factory it's gotta have at LEAST a 2-bar MAP sensor. Running a 1-bar on this car would mean resorting to bandaids like used on Honda turbo kits and the like. Bleeders, etc to stop the MAP sensor from seeing any boost or boost over X number of psi. Doubt Mitsu would set the EVO up this way, especially because they actually have to warranty it

Also, I was under the impression this would use a MAF anyway??

Didn't most older turbo mitsu's ??
