AH yes, I have a superchip, but it was installed before I got the car, so I am thinking maybe it needs to be recalibrated ? Ya, I've reset the PCM many, many times throughout installing these mods and some speakers, fixing power windows, and such. The CEL just comes back after about 30 mins of driving or so. I'm just trying to avoid paying the 100 bux it costs to get my proflow recalibrated
