If you've been driving conservatively for a while I would suggest unhooking your negative battery cable for like 10 minutes then hooking it back up and then go out and drive your vehicle like you stole it.
The computer learns how you drive and if you have been driving kinda slow most of the time you have to let the PCM learn again. You may have to drive like that for a week or so to let it learn. You should be able to spin the tires after that along with the SuperChips set at 91.
That's my opinion and I'm sticking with it.
