Hello again everyone! I recently replaced the LIM and the sending unit for the thermostat in my car and left the battery unplugged to reset the PCM, but on my drive home from my shop today, the car felt like it was hitting a bump with the front end when I was accelerating and under boost. The temperature gague was also very high, but when I used a laser temperature reader, the temperature of the block and thermostat was about 180f. The cooling fans are also off, so the car isn't overheating.

I guess my question is would having a bad coolant temp sending unit affect the car's performance? Like if the car thinks it's overheating, will it limit power? Also, is there a relearn procedure I have to perform after removing power from the pcm for an extended time?
