1998 T/A programmer - advice needed. So like the title says, I've got a 1998 Trans Am; as a brief overview on what you might need to know to help out...
-Pacesetter Headers 1 7/8" longtubes (no egr, no check engine light either)
-No cats (again no check engine)
-3.73 Gears (because of the previous owner, an extra 30k miles is on the odometer... great.)
-seems like its running rich, but maybe thats just the lack of catalyst; Better than Lean I suppose?
I was looking at Diablo and Superchips, but both seem to lack a 1998 version of their tuner. I've been told 98 had something very different in the PCM from the rest of the LS1 F-bodies?
So I was looking at getting a HyperTech Max Energy tuner, hopefully I get some horsepower out of it, but mostly I want the speedometer fixed! (It says 90 when I'm going 67ish on the GPS)
Suggestions?

get a mail order from frost or the like, or a dyno tune. handhelds are junk, all of them
fwiw i've had some frost mail order tunes strapped on the dyno here with great power and a/f ratios that were spot on. He knows what hes doing for sure
