Yes its tuned,the bypass was working when it was tuned,it has some serious computer ecu ground issues that may have contributed to a rich condition.When it was tuned wot was 11.8 and cruise was 0 to 1% rich on the fuel trims threw out the entire rpm range.Tune WAS spot on,but as stated car has some serious electrical gremlins.
