Not sure if this goes here-had 42 lb injectors installed and the car retuned (put down 450 hp and 436 trq) on the way home my speedo wasn't working, then at the driveway a check engine light came on, I scanned it and 2 codes showed up, P0122 TPS sensor A circuit low input and P0500 vehicle speed sensor A malfunction, so when I replace the tps do I have to elongate the holes to get correct voltage or not and can the tuner fix the speedo?
