When are you going to install an aftermarket efi? Have you thought about map-ecu? It just replaces the AFM. Basicallly it modifies the signal from an air measuring device (like your AFM) and sends the modified signal to the ecu. might be worth looking into.
And its fully programmable with boost...
French cars are shit and shit expensive to service and bloody awful and unreliable and expensive and friends don't let friends drive french cars and you wait years for parts.
This car is my daily driver and its set up is intended to be inexpensive, reliable and easy for others to duplicate. I don't want to complicate it.
My other GTV6 is being built with more exotic stuff, intercooler, engine mangament (I have not decide which one) and so on.
Of course with customer cars, my pending move to Tulsa, my wife pressuring me to get the Spider supercharged, all combine to push my Brown GTV6 to the back burner.
It's simply the angle at which the air comes out of the supercharger. Depending on your installation one may be eaiser to hook up than the other. Of course this is really a Vortech thing and as centrifugals go I like Powerdyne and ATI.
