I am running the Go-EFI-8 with timing control, using a locked out MP electronic dizzy, and an old MSD 6AL.

No problems so far. Although the FITech only has 3x3 tables for spark, and 3 of those are defined in boost, so useless for NA guys.

I am only able to get 9mpg on my 493 so far...need to improve that a bit still

Faster, Faster until the thrill of speed overcomes the fear of death...

71 Swinger - slowly collecting dust/parts
66 Belv. II - just a streetcar
88 Mustang - turbo LS beater
