Was told to get ahold of you concerning an ESC module for an 87 GN (HKP calibration). I have 2 for hotairs but the calibration stickers are gone off of them. The part numbers are 16022614 for the hotair and the 87 is a 16051654. Do you happen to know the differences internally? I wanted to try a hotair part and see if it totally changes the car but not in a bad way. Any help is appreciated.
