I'd gap the spark plugs to 0.028" and see if that helps. You'll want the plugs gapped evenly with your Trifecta tune. Remember, the tune is 91+ octane only!!! And, datalog the tune before playing around with it! Give the car about 100 miles to adjust to the tune, then datalog it and reflash it if needed.
