I just put an M90 on my DOHC cobra but i doesnt work right. I figured people that have done an M90 swap on a V-6 might know more about this than the SVT guys. The car starts but dies and makes vacuum instead of boost
thanks for your help.

You probably have the pulley rotation on the s/c going in the opposite direction. Thats the first Ive heard someone making vacuum instead of boost. Go M112 instead if your gonna add an Eaton to a V8, youll get way more out of it.

You'll pull vacuum at idle. Once you go WOT, you'll make boost.
