Lol consistent to say the least haha. And I know you're worried about warranty but I'll tell you this, I talked to a service manager and they can tell if the car was tuned no matter how you tune it. Piggyback,ecu,Reflash,whatever. So I would just go the best route. Tune the ecu. If the dealer resets it, they'll put the tune back on again no charge.

lol yea, but with a piggyback you can just unglug and replug it back in before/after services
plus im not sure how many tuners will be so nice as to reflash my car over and over.
