Tuner Inquiry

It won't automatically void your warranty ... you should read the Magnusson - Moss Warranty Act.

In short, just because you add a part to your car ... it doesn't automatically void your warranty. The part would have to cause a failure to the vehicle & an investigation would have to ensue. The OEM would have to conclude, at the end of their investigation, that indeed the part did cause the failure & then they would be able to void your warranty ... but not the entire warranty. For example, aftermarket rims won't void other aspects of your warranty.

Here is an article that we did on the CAI:

I run the Steeda combo and tune on my car. First, it's a blast to drive. I drive around with the 93 octane all the time and throttle response is picked up all around. It feels like a more eager engine, not to mention its plain faster than a stock Mustang. Steeda also has a tune for life program like most, so each time you add a bolt-on they can refresh your tune to get the most out of it.

To your point on warranty, TJ is right. To void the warranty, an investigation would have to find the CAI or your tune to be the causal part of the failure. Ford has a TSB out for our cars to the dealers instructing to check for aftermarket PCM calibrations if it comes in for warranty engine work. While the computer does keep a "thumbprint" of each time it is reflashed if you were to seriously investigate it, flashing back to stock prior to warranty work will not through a DTC from my experience (used to work at a dealer)

I would check with the dealer you plan to bring the car to as to their thoughts prior to the tune. Some are cool about modifications, others, not so much. If you find your dealer is going to give you a hassle every time you come in for the upgrade, don't do it. (or find a nicer dealer! lol)

I have a 2013 gt 5200 miles on it iv done roush axle backs an eibach pro kit barton sifter a staggered set of ace alloy convex.. I had the oil changed at the dealer I bought it from.. and asked the service manager about engine mods.. I too have a big warranty. he told me if I have them upgrade with ford motorcraft race parts im good.. he also told me if I do a cold air tune if the tune caused the problem its on me.. but if its not the tunes fault warrantee still is good

Ford is going to tell you pound sand for 99% of any issues that pop up with your motor once tuned, so choose your tuner carefully and beat the brakes off your non stop and you'll be fine.......
