I have a modified Pro-M Racing system, it uses all my old sensors, old trickflow manifold, TB, etc except the O2 which are now wide-band with gauges. What I got was a modern Ford ECU, clealy marked wiring harness, Wideband O2's with gauges. There is a little setup with a laptop at the beginning very easy. There is a about 40 min video the website, good education on how Mass Air system work during an installation on a Fox Body Mustang. I had a little issue with one of the O2 sensor which was my own doing. I'm 99% sure I have it under control now after welding in a longer bung to protect the sensor and protecting the O2 sensor connector from heat and vibration. I was running a vortech supercharger, s-trim however the seals failed and I have it off the car now, I made zero changes to the computer, change my plugs one heat range hotter and that was it. Since the Pro-M system measures air going it doesn't care if I have a blower or not. I'm pretty happy with what I have, the support from Pro-M Racing has been great too.
