FMU question

[FoMoCo1]

are paxton and vortechs FMU internals the same?

thanks for any help

I have personally had these two apart side by side and visually they are the same. I didn't bust out the dial caliper or anything but if I was a betting man I would say that they are the same. You should be able to use vortech tuning discs and diaphrams in the paxton housing contrary to whatever paxton says.

Now for my usual line. "FMUs are the devils handywork"
