I have one 87 MAF for sale. It has one screen in it. At low boost 17 psi it will go to 230 G/S which will be fine if your not using WB correction since erics chips lock on to 255 under wide open throttle conditions for consistency. it will work with the 6.0 chip fine but not if your using WB correction. pm me if you have question.
