What are you talking about? You have already bought and paid for your engine, what Ford does after your purchase will not affect you. If a tune is CARB certified, they cannot deny anything. If their system malfunctions while reading the tune and ruins something in the drive train, that's on their dime. IF you also modify something outside of the approved tune, its on your dime. This is no different than in the sixties, when everything was done mechanically, instead having a computer sampling many more parameters' than was possible then, and making adjustments in the fast lane. This how emissions and gas mileage has gone for the better. Remember, the manufacture makes the tune for the safe side, that will fit most applications with good results. Lets face it, a 10 ton truck, with a cab and box van, is no way near the frontal area that a motorhome has, or the height. Ford does have specific chassis for designated applications, but improvements can be made, for both safe power and economy. If the tune is approved and certified, it will not hurt the drive train.

Magnuson -Moss Waranty Act wont help you at all Ford will win every time. The money you will spend on attorneys would buy you a new motor 2 or 3 times over. I have first hand experience on this after Gail Banks lied to me that they would help support their 6 gun tuner. I spent more on attorneys than my truck was worth.

Exactly right. Camping World sued Dodge in 2000 after a fuel injection pump failed on my 1998 Dodge Cummins following a Banks upgrade. Although I had a letter from Banks stating that their products would not void my warranty, they immediately defaulted. Camping World lost the lawsuit and discontinued selling Banks products for almost 3 years following this incident.

Defies logic how?

A--I can make an otherwise desirable product that will void the customer's warranty. But some won't care about that, others will be unaware of it and I can mislead others about it.
B--I can sell the product for as long as I can and make some money or not sell it and make no money.
C--I'll sell the product and make money.

How's that reasoning for you?

you only quoted part of my statement.

for my part, seems like we would've heard from owners who bought the 5-Star product and subsequently had warranty wirk denied due to the 5-Star product and yet i don't recall any such posts. anyone? look, i'm not a shill for 5-Star and i am considering the purchase. i wondered about my Ford warranty too and if anyone is still unsure a call to Ford Corporate may be a good idea. defies logic that a company selling this product where the installation and use voids the mfg warranty

Also, I've never heard anybody's V10 being damaged by a 5-Star tune.

On F-150 Forums I've read of tuned engines being denied coverage. I'm sure both of us have never heard of many things that have happened.

In any event what matters is that Ford seems to be in a position to deny coverage to tuned engines. Knowing that, do what you want. But acknowledge you're possibly putting your warranty at risk.

this was my earlier point. seems we would have heard of denied warranty claims by Ford by now if there was a problem.

I have a diablo predator. It is possible to cause detonation if I manually adjust things too aggressive. But I've had my tune installed for the last 275,000 miles. I have 425,000 on my V10 now. I think you'll be much happier, and the chance of anything going wrong on your V10 is pretty slim.

Whatever the vendor says about warranty is worthless. The only voice that counts is Ford Corp----------------not even a dealer.

Things that revise the shift points and ignition curves, as most tuners do, can easily adversely affect engine and transmission life. Use these things at your own risk.

So I wonder why it would void the warranty on a truck and not an rv ???
