What stat differences have you seen? Have you taken it in to see if the Ford Dealerships are going to void your warranty?

I have looked at several threads and I have seen people say

1) it voids your warranty
2) Just tell the dealership you had autozone run the "check engine light" codes a few times
3) Dealership is fine if the tuner isn't what caused the issue...

anyone have any idea?

 

Like a H&S tuner? No, nobody would do such a thing.

Pay to play they say. You tune, be prepared to fix it yourself depending on what breaks

 

I'm sensing sarcasm haha. Well considering I got the 100,000 mile warranty it's probably not worth throwing a tuner on it?

 

Stop in here sometime, a bunch of us are h&s tuned
