I have two 1980's TPI ECM's 1227165...one has PROM "AUM" and the other "AKFM". Is there a web source where I can determine the calibration of these two PROMs?

Any recommended sources for custom PROMs?

i believe the aum is from a 86 fbody 5.0 tpi and the akfm is 88 305 at trans 2.73 gears.

Thanks..that really helps...now I need to find a source to program a PROM for me. My engine is a 79 Vette motor, with Crane Energizer cam (forgot the exact specs), flat top pistons and 1988 center bolt 58cc 305 heads. Taking the quadrajet off and installing TPI. Will be looking for a set of 350 (22lb) injectors.
