Don't try this at home kids. Take my word for it, and Turtle'*, the Jet Stage 2 REMOVES the top end limit. 137 mph is spooky. The drievtrain will do it, but the handling wasn't intended for that speed. I have wide-open country roads where I can see for miles, and it was STILL a helluva risk. Huge difference between 110 and 137 in handling. The front end of the car gets really light at about 120. Major spooky O **** factor above that.
Buckman, I ran a stock PCM until today. Don't mess around with the stage 1. You'll just mod later, and wish you'd bought the stage 2. Jet recommends Intake, exhaust, and 180° thermostat before stage 2. I'd add an additional tranny cooler first, too. Protect the investment.
Pontiac1983, any auto parts store that knows what they're doing should be able to cross-reference the proper thermostat to a 180°. Don't forget the rubber seal while you're there. Then go to the Pontiac Dealer and get the gasket. Most auto parts stores won't stock it.
Turtle, break a leg. You take it. You can have the crown back! I like my car and the father of my kids to well to do that again.....at least until I get new tires!
Cny.....what'* it feel like? VERY spooky above 115-120. Butt-pucker spooky. One little rock could ruin your whole day, or a thrown tire weight.
