2008 Challenger with Whipple
Customer brought the car for a re-tune because of startup and driveability issues. We did a baseline pull and were shocked at the a/f, it pegged out the wideband at 9 AFR it was so rich. We redid the tune and ended up making more power with less timing. This was from tuning only no parts or anything else changed.
