Exactly What @LokiWolf said. In all of my research on Tuners, before I went the 5 Star route in April, (and there are many threads on this forum to educate oneself), I do not recall any 4th Gen having a warranty denial due to a tuner. Please correct me if I am wrong, my recollection seems to favor more positive results as I age.

I am not aware of one either.

Funny thing too, as to @LokiWolf post, I recently took mine in for the 21B10 update. about a week prior to taking it in, I removed the tunes so the vehicle has time to "cycle" many times so the ECU looks clean. Funny enough, they called me right before they did the update to ask if I "had a tune" as the update would wipe it out. I found that funny for two reasons, first off, you would think their PCM flash tools would tell them immediately if the PCM was tuned. Second, I thought it was nice they actually thought of it before they flashed the PCM.

The Service system will flag if the key cycles is less than when it was recorded last(Last time you had in for Service), but some Tech's will ignore it. With the physical mods you have it would also be an immediate flag, and a good Tech will ask. Some tuning devices won't let you retune, if they overwrote your tune, because it thinks it already did it. Sounds like you have a good one! Keep them!

Thanks for the advice. Looks like my expy will stay stock. I was just messing with my Duramax and saw my chip and wondered if there was a chip for the expedition instead of a programmer.

Iv had a 5 star tuner in my 2018 expedition for 40 k miles with no issues. Thier customer service has been stellar. I wouldn't drive this thing without it. A chip would never do as much if they even make a chip for these. 5 star is great.

+1 for 5 Star. Been running just a 87 daily tune and it’s been great. I mostly wanted it to change how it shifted. Mission accomplished plus some extra scoot is just icing on the cake.

Again, like I said above…they do make a chip for these. The JMS boost max works on all Ecoboost Expeditions.

Any company that tells you that the dealer can’t tell it was tuned if you return to stock should not be trusted. Period. But hey, I use a tuner that doesn’t lie to me.
