Hello/Beat that dead horse again!

[BluVette]

As a new subscriber to the list I just wanted to pop in and say hello to
everyone. I own a corvette restoration and performance shop, and I am always
looking for a better way to do something. My current project car is a Paxton
supercharged, stuffed to the gills 355, 1989 Corvette L-98 engine, with 30
lb/hr injectors, and a fairly radical cam, with estimated HP in the range of
600-650 BHP.  The stock computer with a privatly burned chip in it is
working really well (esp. since most everyone said it could not do it.)
Anyway, the only small problems I am having with it, is it is idling
(hunting) between 5-700 rpm, and I need to get the idle up to about 850,
with this lopy cam I designed for the engine. The other problem is with the
built in rev limiter, keeping the rpm under 5400, and this needs to be
raised to approx, 6400 rpms
So, who's got what suggestions, and who's the most reasonable person (that
knows what they are doing) to burn a new chip just like the one currently in
it (i.e- they need to be able to "read" the chip that is in there now), and
then make these two corrections to the programming?
Any ideas or suggestions? Someone in the general Louisville, KY (say within
200 miles), would be a big PLUS!
TIA
