I have never had a tuned engine. I have always run stock & have had no problems with catastrophic engine failure with any vehicle I have owned.

 

Yeah aggressive tunes on turbocharged motors, regardless of brand, have the increased chance of issue or catastrophe like this (especially as you get up in miles, more so if the miles were hard). I’ve kept our Focus ST stock for this reason, same with friends with their RS who would only ever think of going with a conservative Mountune tune, which has Fords backing I believe (plus since that one is an open deck design can’t go overboard anyways).

 

I don't get guys who want to pretend their pickup truck is a race car. Driven conservatively (like a pickup truck) and maintained, any of the F150 engines will get you to 200K miles and beyond with little problem. Tune it and drive it like a race car, expect race car problems.

 

Imagine that! An aggressive tune might cause an engine to grenade when something goes wrong. It could likely even happen to a stock tune engine when something goes wrong.

 

Crazy that aggressive, risky tunes are risky and aggressive! Next, they'll be telling us that going off jumps is bad for suspension parts!

This is not news, nor has it got anything to do with fords in particular...any modern turbo engine is tuned to the safe limit from factory, and the more you crank up the boost and fueling the closer you are to melting or grenading things. Bet it's good for views though!

 

This is a little dramatic. Of course there's risk but if you use a reputable tuner, the risk is very low. If the tuner doesn't know what they are doing and focuses on horsepower alone, sure you'll blow the engine. But saying "Ecoboosts can't handle performance tunes" as a blanket statement is not true.

 

ANY tune WILL shorten the life of an engine. With all the competition between Ford, GM and Ram the stock tune is the best compromise between performance, MPG and durability.
More aggressive tunes just rob from Peter to pay Paul.

 

This is true, but to what end? Shorten the life from 450k to 425k perhaps? Or 200k to 195K? Nobody really knows for sure, and most don't even keep their vehicle long enough to find out.

 

You are correct. Except for the guy in the video, he knows LOL. The only ones that know expected life of the engine are Ford, GM and Ram running the engines at various tunes to find the best compromise. Answer we don't have is it 200K miles? 300K miles?

Didn't Ford do a promo on the 3.5 years ago stating it ran XX number of miles without issue?

 

The video doesn't go into the tune, other than say it was aggressive.
Was it done by the owner, mail order, etc. ?
I have been running modded " tuned " engines, ( not in my truck ), since 2012, if done " CORRECTLY ", there isn't any issue.
The person who tuned my car(s) used to work for Ford, as a calibrator,.....
.........it does matter who & how the tuning is done..
