clifornia 6.0 warrenty

[jimted79]

Has anybody out here in cali tuned there 6.0 and then put back to stock and got warrenty work done? I want to buy a 6.0 and put a mild tune and cat back exhaust for a little more power and better mileage. Right now i have a 04 f250 with the v10 that gets 13 over all not loaded and i heard a bone stock 6.0 dosent do much better. If i'm going to kill the warrenty to get that 20+ mpg then i cant see spending the extra money for a diesel and the maintenance.

I have an 04 that is progammed and have put in back to stock and had warranty work done. However I have heard of the dealership voiding warranty's because they have determined the truck was programmed at some point. I don't know how far they have to dig to determine this, but a friend of mine who works for a Chevy dealership said they can determine the last 10 programs in the pcu. I am not sure this is the case with Ford, but hopefully someone with more knowledge will respond.

I pulled off my mods before visiting the dealer for warranty work except for the intake. I did ask the tech point blank though about how they handle mods and how it affects warranties. He tells me at that particular dealership they don't get uptight about mods. In the event that a mod may be the cause of the problem, like if they suspected the problem with a mass air flow sensor was an aftermarket intake ... they'd actually return to the truck to me to give me so I could return the intake to stock and then rediagnose the problem. Sounded like a pretty friendly attitude to me... much better than a voided warranty.

Dont expect to get 20+mpg but they will get a lot better than the v10. I average 15mpg going fast and with a lot of city driving. Also, I wouldn't waste the money on a cat back exhaust. If your going to spend the money on an exhaust get a turbo back.

the new trucks leave a footprint, the older ones dont... you will be fine... but if you are going to run a catback only exhaust, get a cat delete pipe so you will lower your EGTs and get all the performance out of the truck....

dont sweat warranty because if the dealer wants to be a DIICK, they can void it because your tire tread is too low, or you changes your oil in longer than recommended intervals, or if you didnt do them at FORD and you dont have your records... just find a mod friendly dealer and have fun...
