ECU flash???
I am a newbie here. I see all the talk about tuning and the great hp gains that are achieved. I would love to jump on board with a flash but how does it affect my warranty? Does anyone have info on this?
Thanks!!

If the dealers find out it will affect the warrant. But its highly unlikely they will if you just do an ecu flash.
If you do an EC flash you could revert back when u take it back to the dealers.
