I use msd with timing lowering as boost goes up. It works fine with my supercharger. Timing set at 12 to 14. The msd box is not that expensive, its not the programmable one though
What year is the car. The Fox body mustang does not get much inspection anymore. Just lights etc. Basic safety stuff. I have a 1984 that was inspected in February with no cats and had no issues.
I was under the 84 fox and saw the flywheel a little exposed. Is there a piece missing or should I just get a plate and cut it to fit? Or is leave it alone an option?
