The car had some idling problems today and stalled several times. However, since late this evening, the car seems to have stabilized and idle appears very close to normal. I spoke to JET and they insist that their chip isn't (or wasn't) causing the problems, stating that their program doesn't affect idle. They suggested waiting for the car to stabilize without the chip, then reinstalling. JET representative said that maybe the computer was too "confused" with the addition of the headers and their program having been already installed in the computer. They further said that the computer might "better take" their program once the stock program has stabilized with the headers. Does this make sense to anyone?
You can be Phil too if you'd like.
