Longevity of High Power Tunes

[Burner5509]

Do the 250 - 300 hp tunes over stock hurt the life of the motors or transmission. I'm not putting my foot into often but just wondering how these motors and transmission will handle the power over years of use.

I watch all of the gauges and what not but have a concern since rebuilding things isn't cheap. I only have 42k but it is something to consider as time goes on.

The 6.4L motor and the 5R110 transmission can take some serious abuse. Issues seem to be hit and miss. If you are hard on your truck, expect issues. Clearly you are not, so you shouldn't have any issues.

The best thing to do is not wait for something to fail to rebuild it. Start saving for a studs and transmission parts (maybe valvetrain parts too if you want ultimate reliability). If you start saving now, you'll probably have the parts and money for labor before anything ever happens to the truck.

Your tranny will be the first to go if anything. I got 96k miles out of my stocker. Truck was tuned at 35k miles. I tow a good bit in the mountains, so it was only a matter of time before I killed a tranny. Heat is the big cause of failure. Keep your temps down and your tranny will last alot longer. As for your motor, it appears you have already deleted, so you have already taken the first steps to a long lasting motor. Dont hot rod the hell out of it all the time and you wont break stuff.

From what i understand these tunes change fuel timing and the amount of fuel that is injected into the engine. You may be only seeing a few pounds more of turbo boost but the pressure in the cylinders will be much higher. This can lead to problems. As said earlier save for studs and don't drive it hard all the time. I have one of the hit trucks that will puke coolaint anytime I mash the peddle.

At what point are studs needed? I don't feeling dropping the 500 just to do so. I would think Ford built the heads to withstand a hell of a lot compression since these motors came with twin turbos.

In mention of valetrain parts to the degree of axles those are beef. If I had 4d's and come out spinning tires then I would upgrade the shafts but in that respect I think those are golden.

When I tow I only allow the trans to be in the low 170's and nothing higher. Just driving I only see 160's and down. My longest daily drives are to work at 12 miles on way.

$500 in parts. A shop will do studs for around $2k...

This still hasn't answered the original question of when they are needed.

That's a very cheap price. Id be skeptical to go there. Alldata calls for 23 hours for head gasket job. They would have to be only charging like $30 an hour in labor at that price. You have roughly $530 in studs,$350 in head gaskets, $160 in injector fuel tubes/seals, $80 in turbo seal kit, coolant, oil, power steering fluid, trans fluid. And maybe more miscellaneous.

Every engine is different sir. If you run a low tune like 175 or less you may never. Big tunes will eventually need them
