currently in my car i have a procharger d1 w/ dynotune wideband, i took 4th gear to redline and everything was normal and i upshifted to 5th and the wideband went to ~18 when normally under boost its near 11-12, so i let off and the wideband goes to 50, even with the car running w/ no boost it just stays at 50.x and doesnt go back down to ~12...this is the second time it happened to me in the past week, and also when i turn the car off and back on it returns to normal...could this be due to a sensor malfunction, or better yet what should i look for, the car doesnt knock at all it runs fine w/ the wideband at 50 but iver never put it under boost when it does that cause im not a fan of replacing motors...any help would be appreciated.
