i dont know for a fact, but i think you need a vac operated one. reason i say that is because a buddy of mine had an issue with his because his MAF sensor was metering the air and when the valve released the pressure it made it run like crap because the air was already accounted for in the computer, then the pressure released and it ran rich IIRC. his was on a mustang though so might be a bit different, but worth looking into if it were me. he had to get a blow thru MAF sensor and mount between the TB and supercharger in the tube. like i said, i don't know if our MAP's act the same way or not, so maybe someone can chime in and clarify it. either way, i love the sound of one! lol.
edit: actually now that i think about it, i think you will be ok....MAP = speed density system, not air flow system. of course, the easy way to find out is bolt it up and see what happens
