So I’m in the process of buying a 2020 XLT, with the 3.5 eco boost, of course. I’m curious on what I can and can’t do that might void my warranty. I’ve heard and read many different options. I’m looking to get some more performance out of my eco boost motor but don’t want to void the warranty. I’m thinking intake, throttle body, tuner, boost control, exhaust. But I don’t know what would void my warranty. I’m used to owning used cars and doing what ever I want with them because they’re not under warranty and are paid off usually. This is my first brand new vehicle and I want to mod it but don’t want to loose the warranty or have any issues.
I was told from a mechanic friend of mine that any tuner that flashes the ECM will void the warranty and they can tell when you bring it in for a warranty claim. I’ve also read on here that all you have to do is put the stock tune back on and disconnect the batteries for 30 minutes and you’re good. I find that to be a little silly but what do I know. So any advice would be greatly appreciated. Thanks!
