HP Tuners
get my automatic shifting like a sports car and
tweaking up the spark & open loop / PE fueling
by "feel". It's solid. I know on their discussion
board there is at least one guy who's gone and
dynoed before/after. But the key there is not the
software (as long as it's got the access you
need, which it does) but in knowing what to
mess with and how much. That's got me going
slowly in the fuel map tuning especially.
I've had a couple of PC communication issues but the company seems to be pretty responsive to problems you have.
