Re: Chip or a flash tuner
Question is if you want to retain your warranty or not.
If you get a chip it is going to have to be piggy backed to the one you have in there now. Ford will void the warranty on the car if they find you have a chip in there.
Of course when you do mods and make the changes with a tuner you can put the car back to regular parameters and remove the mods if there is need to have warranty work.
One draw back to a tuner is you can make a limited amount of changes but not a lot. Some changes are just not recommended for a novice tuner.
