Hey. OBrien2, this is Ghost. The SES is low voltage from the air mass sensor, it just needs to be cleaned with circuitry cleaner. It's a Granatelli.

Actually 18.5K is what a CLEAN used SS is worth without the SLP package, I got more than that because it was a custom built SLP from the Y2Y form. It's got the fiberglass hood, 1LE package, Auburn rear instead of the Zexel Torsen, Bilstein suspension, ultra light driveshaft, supplemental door latches, etc. from them.
The build # is 4204. Thee was actually only 6 of them made in 2001 that had ALL the Y2Y options mine did. It was on their calendar in 2002 and 2003I used to have the breakdown on my site www.ghostrider.cz28.com

The aftermarket mods are...
SLP headers
Random Tech cats
Flowmaster muffler
JET skipshift eliminator
BBK throttle body
Granatelli air mass
Richmond 410 gears
NAPA ceramix brakes
Centerforce Dual friction clutch
Granatelli strut tower brace
SLP subframe connectors
DMS Panhard rod
DMS lower control arm

some other stuff I forgot, and the Lingenfelter cam I sold
The car has 16K miles... it was babied. I've gotten 12.60s N/A (even with my big butt in it, but the best slip I can find is the one I gotta stand by). The only reason they got it from me is because they made a DEAL on the black C5 Vette I'm in. The price is a little steep, but... Vette was all I woulda bailed on it for. Just replace the solenoids and bottle and you're good to go.

Call 727-328-5155, and talk to Dave Johnson (Fleet Manager) if you want to deal; he'll work one for you.
