I doubt u noticed that big of a difference. Your problem is probably from not disconecting the battery for 15 mins after the swap. The computer has to learn the different parameters for keeping an idle. It will eventually go away, but it will be quicker if u disconect the battery.

pullies don't really have any effect on idle quality or rpm. think the problem is elsewhere.

A quick was to reset the computer is disconnnect the batter and hit the brakes a few times and hold them for a few seconds. It will drain all power from the ECU resetting it. Then just hook the batter back up. Should take you less then 5 minutes total.

FYI -
You can also turn the headlights ON and then disconnect the battery to remove all voltage from system!
Just remember to turn the lights OFF before reconnecting the battery!
I just put the pulleys on the 98cobra and they do make a nice "seat of the pants" acceleration improvement!
