I recently supercharged my M3 and went through the break in period of 300 miles. I wanted to test it out I hit 4k car goes limp,and EML,DSC & ABS light illuminate on the dash. Take a scan of the vehicle replace front "TPS" EML,DSC & ABS light disapear. (code was P1637)

Okay, I believe the issue is resolved at this point. take the car for at test drive get up to about 6,000 rpm car has a slight power cut, or stutter and gets to about 6800 and hits limp mode again. The car then idles like a V8, SES illuminates on the dash. No EML or DSC or brake light (abs). I scan the vehicle again, P1637 comes up. How can it be another TPS code if theres no EML,DSC, ABS lights? the only thing lighting up is the SES. No I checked the throttle linkage and clamps nothing is being blocked there. Spark plug gaps are good, Coils have been tested and are good. I am aware of the other two TPS one under manifold other is the pedal. But if it is one of the other two sensors wouldn't the other lights come up like they previously did before, when I replaced the first sensor? HELP

NVM, in case anyone else has this issue try clearing the code with an OBDII scan tool, then flip the TPS near the oil filter housing upside down. Plug in I assume it is due to the fact that the heat from the oil filter housing gets to the sensor wires. Took the car up to 8100 with no issues, I will post here again if any issues re occur.

Im having the exact same issue with my recent supercharger install. Did this end up fixing your issue?
