I have the evolve tune. Got it back over a year ago. Gets better mileage now and more power which can be a detriment in the winter but I like the tune a lot.
Never ran the piggyback. Went straight to the tune right after Concentric got tuned and posted the dyno.
Was the best decision for this car. It's how the car should have come programmed from factory.
