Revo tuning for 2006 4.2 S4
I recently took my 06 S4 to a local tuning shop who flash Revo software onto the ECU, and then they put the car on the dyno to test it. The HP and TQ measurements actually went down and they had to flash the chip back to stock settings. Any thoughts about this? The people at Revo couldn't explain it.
