Not always my friend. I am not against modders but its silly as a modder to think that my warranty might not be voided. I will say this once, it has the potential to get VOIDED, not a for sure. And heres how it works, because you hook up a tuner and dealer finds out they will not necessarily void your whole power train warranty on the spot, can they, i am sure they could but probably can. And yes yes I know some of you will get a lawyer and fight that, whatever, ford has more money than you. Chances are this is how its going to work. Say you blow a radiator or turbo, they could say that your tune was the cause and would not cover it, that is what is more likely to happen. I know my dealer is quite stringent and I have had to fight them on a few things that I didnt even mod because they thought I did. So it depends on a dealer. But you start talking blown engines and turbos, that means a Ford Rep comes out and the choice is no longer in the dealers hands. Friend has heavily modded his diesel into a raped ape. His dealer is cool, but told him if a ford rep comes out hes on his own.

I have a tuner on my new Camaro, thats my choice but as soon as I plugged it in I made the conscious decision that this could void my warranty and will not complain if does. The Camaro Forum that I belong to there is a list of threads longer than you care to know of guys with mods where the dealer cut them off. Its true, run the risk if you like, if you think adding a few HP is worth a voided warranty go for it. The problem is these days is that the vehicle PCM and the computer they use to check it is becoming more and more sophisticated and can figure out what has been to it. The PCM's these days are not like the ones in a 1995 Chevy lumina where it could tell them if a code had ever been thrown.

The thing is look at the TSB that the guy posted earlier, manufactures want to know if there stuff is being played with. Guess what modding vehicles cost them money and in turn the cost is passed down to the consumer. I am not against modding, I have done it, but I think we need to come to the conclusion that if we do, the maint on a vehicles is our problem now. Personally a tuner on a F150 is just silly, but if thats your hobby and what you find fun go for it.

 

My dealer has told me flat out that there is evidence if a PCM has been accessed just like any computer, and if those tracks are there, my warranty will be void. Ford is requiring this of dealers before they will pay dealers for warranty work.

 

bluejay you are right my friend. And yes there is black box and it will tell them

 

I had a good discussion with a custom tuner up here....
He told me flat out that any tuner hooked up to a truck can be tracked,no matter if you return to stock when going to the shop.
When a guy who has been doing this for 20 odd years says this stuff I tend to listen....

 

Thankfully, Ford is finally selling me a truck that I don't feel the need to mod, just to make it perform reasonably. My 2005 ran so poorly from the factory that a tune was necessary just for reasonable, normal performance. It would hardly downshift at any speed, before the tune. With this new truck, it runs great from the factory. Shifting and downshifting is as it should be. I just dont feel the need for any change to its performance. In fact, I am concerned that if I start messing with it, I may kill the great gas mileage I'm getting.

 

Yup neighbors 2007 Mustang Roush 427r had this happen. Decided he wanted to tune it about three years ago and went through 3 tuners to get it back straight and it still didnt run right. Well finally the PCM fried, went to the dealer, got the middle finger and walked out of the dealer with a new $600pcm plus labor. Why tune a Roush thats already tuned IDK. But moral of the story they do know. And the last tuner he had put it back to "STOCK." before it went in.

 

Back to the topic, 5.0 vs Ecoboost VIDEOS. Im surprised nobody has done this and posted it on youtube.

On a side note, I dragged a 4dr Tundra this morning. Looked fully loaded, had the trd sticker on the back box. Anyway, when the light turned green, we both gunned er, both trucks were dead even, as far as I could tell, until I got to the first turn doing 60mph, I let off. I got the 5L SCREW FX4. I love the accelleration of the new truck and was surprised I couldn't take the Tundra. So I looked it up online, the truck must have been the 5.7L V8, 385HP and 410FTlbs tq

 

Exactly what I was trying to say to him... the 5.4 3v's were sucky out of the box, love mine tuned now, but I also bought mine at the end of the warranty anyways so it didn't matter.

 

It seems Jap junk has improved over the years. But i still dont like the looks of em, and cant fathom buying one ever. I just cant see being looked at seriously showing up a boat launch, job site, hunting camp and look legit with a titan or tundra

 

I sold my diesel for my 5.0. IMO the turbo lag on the truck i drove was just as bad as my powerstroke.

 

The lag on the one I test drove was pretty severe. Plus, the steering felt very light when making quick adjustments. I could have gotten used to the steering, but the lag was not something I could tolerate.

Seat of the pants performance compared to the 5.0 felt the same except for the lag. A friend that worked at the dealer had pretty well sold me on the EB until I drove it. The two trucks I drove were identical except for engines and I drove them over the same route.

 

I had an 08 which had the twin turbos and it was better than my 07 with a single. But what I come to find out with turbos the more you ease into it vs pedal to medal you get less lag.

 

On our freeways and two lane highways, easing into it most often not an option. You go when the chance presents itself or you better not go.

 

I more or less meant being a little more gradual with it vs literally pedal to the floor. Which if you have to do pedal to the floor every where you do, then that must suck

 

Get the new EB with the big fuel tank and you are right back to over $100 fill ups just like your old diesel. But I agree, everything else maintenance wise is way too expensive if its a daily driver.

You need to take a little bit of your own medicine when comparing the EB to the V8s on the market. You say you cant compare a modded engine to a stock engine but yet you are comparing a forced induction engine to NA engines. Its not rocket science or completely out of this world for a V6 (or even a 4 cylinder) to outperform a V8 when you slap twin turbos on it. So to say how impressive it is that this "little v6" outperforms the V8s really doesn't mean a whole lot to me when you are looking at a twin turbo FI engine and comparing it to a NA small"ish" displacement V8. Not really that amazing to anyone who knows anything about the automotive world. I agree though, the EB is a great step in power/efficiency for a full size truck.

What it boils down to is we have a TON of people trying to compare and go to war, with two engines that are really apples and oranges.

My issue is that we have all these EB owners talking like their truck is the cream of the crop but then when you bring up some modifications the argument turns into "well I'm talking stock vs stock".....1st of all, if you want bragging rights about how fast your ride is, don't buy a pickup, secondly, if you really want bragging rights be willing to drop the coin and effort into making your vehicle faster....because there are a lot of people out there that are going to MAKE SURE their 5.0 stomps any EB on the road, and the argument that the EB is faster off the show room floor is going to hold no weight.

Nothing personal...Im just tired of seeing all of this back and forth arguments comparing apples to oranges...because if you made the orange (NA V8) into an apple (forced induction)....it would outperform the original factory apple.


In the end they are both AMAZING engines....and I have no idea which one I'm going to buy
