High idle after mail order tune I got a mail order tune from RPM Motors and now when i push the clutch in to slow down or come to a stop the engine will rev to about 2k and will stay there till I make a complete stop. Even after a stop it takes about 10 seconds to finally drop down to normal idle. It will drop from 2k to idle all at once. I just gotit back today because it done this the last time so I would say he didn't fix it. Oh, it doesn't do it with the stock pcm. What is going on in this pcm? What isn't set right?

Throttle cracker is a pretty straight airflow adder
that has no clue about other air sources or air path
model errors. If you have a vacuum leak, a different
throttle body, etc. it will merrily give you more than
you need.
I'd begin with the ported TB, make sure it's closing
all the way (some people especially in the past have
jacked the set-screw or drilled the hole fighting tune
problems, there's yer excess air) let alone the chance
of an "oops" or two with the Dremel on the seating
circle. This year of 'vette is cable throttle, right?
