Community Q&A Question: Pro M EFI question.....

Asking About: Mustang Pro-M EFI Engine Management System (91-93)


Pro M EFI question.....

I have a 91 coupe with a 408W, AFR205 heads, 10-1 compression, Hydraulic roller, Trick Flow R intake, Accufab throttle body, 42lb injectors and Pro M mass air for the 42's. The car has a TKO600 with 373's. Car has old tune on stock AL9 with chip burned. Problem is it runs good but below 2000 RPM;s and at low speeds it kicks, bucks and really sucks to drive through town and cruises.

Will the Pro M EFI system help this or do I just have too much motor.


really frustrated with the car.....

The Pro-M system would help with all of that and more. From your laptop, you'll have complete control of engine functions and you can greatly improve drivability as well as performance. With the Pro-M coil on plug conversion, you could even control spark for each individual cylinder!
