I fail to understand how it could change your rpm. That is impossible. Only way is if your converter wasn't locking up and the tune somehow got it to lock up. 300rpm is about what your converter will lower when locked. Everything is mechanical so no tune will have any affect on it.

Damaged Engine using Tuner

Well going to find out about using tuner and having a catastrophic engine failure. I have a 2016 Georgetown XL sitting on a 2015 chassis. The number 5 piston supposedly hit the spark plug and broke the piston and connecting rod and dumped them in the oil tank. The engine before that was running smooth with no warning. It made a loud hiss like a air hose blew and engine died. It only has 25500 on it and I was real careful of keeping it from doing to many high RPM climbs but you have to sometimes.

Ouch...sorry to hear about that kind of failure!

I'm not a mechanic, but based upon what I've read about tuners, I doubt that the modification caused your problem If I'm correct, the 5 Star Tune typically helps to reduce high RPMs. By any chance did you observe that the tune resulted in an increase in the RPMs? Again....I don't know squat about engine mechanics...just asking a couple of questions.

I think this could just be a case of coincidence. And, I wonder if an analysis
of the piston and connecting rod will show that there was a defect or some type of wear that had been starting to fail for some time. Or you may never know. All you can do is decide to avoid the tune after repairs, or continue with it.

I recommend you uninstall the tune before you take it in and don't mention it. First, because they will reflash your computer when they complete the repairs (just standard proceedure) and your tuner will be locked with the old stock tune and you'll have to get 5-Star to restore it. Second, while the Magnusen (SP?) Law says the dealer can't refuse warranty coverage for modifications unless they are proved to have caused the failure, just avoid the fight and don't mention the tune.

With the damage reported, I would think its already towed to the dealer and removing the tune is way to late.

The Tuner work as advertised. It really helped going up hills and didn't hit the higher RPMs like it did without it. I thought it was a good product and would help the engine instead of hurting it. I really don't thing having the tuner on it caused the problem. This is a long outstanding problem for that engine. Lots of history..

The very first thing I did was remove the tune and put in stock mode. Than I called road side assistance. I didn't want that tune still showing on there when it went in. Time will tell as if asked I will say what tune....

Guys on F-150 forums report that Ford technicians can detect an aftermarket tune was present even though itís been removed and check for that routinely.
