I took my car in for its normal maintenance routine, and took the necessary precaution of removing the 3 bar and putting the stock tune back on. OAR shot to |1|. Once I got the car back home, I put the 3 bar and Gearhead tune back on, and over the course of several days watched the OAR continue to move closer to 0.
This week we may have some good news to share. OAR is slowly progressing toward |1| again. I will wait for it to sustain better than |.8|, as that should be the mapping for max boost. Then it'll be back to the dyno!
