Hey guys as u probably know from reading my other post I'm getting into a new truck because my 09 is being bought back by Ford due to issues. I just ordered a 2011 FX4 ecoboost and was wondering if the Gotts mod makes any difference in the whistle of the turbos?

 

I don't think I would risk touching anything under the hood for fear of voiding the warranty. It has a different intake also, so you may not be able to.

 

Well on the 2009 to 2011 models when I say Gotts mod I'm referring to removing the snorkel that runs from the air box to fender.

 

i did but didnt get any thing out of it in my 5.4 2010 xlt

 

I'm sure u did u just can't notice a gain that little. But I'm more concerned about the ecoboost as this is the new motor coming my way. I did it to my 4.6 3v and notice an increase in intake noise.

 

I urge you to use extreme caution. I have heard that there is to be absolute no warranty on the eco if there is the slightest modification to anything on it. Again only hear say but something I wouldnt be willing to try if it were me.

 

My dealer told me that the techs are Checking ecos with a microscope for mods and then voiding the warranty. Be careful.

 

Thanks for your insight, but this doesnt answer the question at hand. So those that have done this please post.

 

I have not heard of anyone doing it to the Ecoboost or even the 5.0s. Only the 2010 5.4s. Again, I would not do it. I talked to my service manager and he said that changing exhaust or wheels is fine, but change anything under the hood, and you are looking at voided warranty.

 

As others have posted.....

Ford is looking for any changes under the hood.....if changes are found your warranty is toast......

 

This Tsb is for the 5.0 but there's another one like it for the ecoboost>>>http://thehorsepowerjunkies.com/blog...tuning_tsb.pdf

The Tsb number is 11-7-7

The ecoboost Tsb number is 10-2-6

 

Thank for the post, I understand this is normal for any manufacture to send this out to its techs. This is nothing new for the ecoboost or 5.0 every engine including the old 5.4 and 4.6's has had these protocalls. In the end though the manufacture needs to prove that any modification has cause the damage to void the warranty. They have lost many cases in court but have won some too. I'm not saying I will be doing this but rather my question was to those that may have done it if they noticed any difference in noise from the turbos, as many people are reporting with cat-back systems.

 

It would be cheaper in most cases to lose the warranty on an engine, than to pay the lawyer. That is what they bank on. I realize they have had similar statements in the past. The difference now is that they are informing the dealers to stick to the policy and if they don't Ford won't pay the dealer for the warranty work.

 

If you win your case you will likely win a case for attorney fees. But again thanks for your information, but not what I'm asking.

 

I addressed what you are asking in post 9. All the other was extra. The only one that I know of that has modded their EB at all is Mr. Tea. He did the new complete intake. Apparently, the warranty is of little concern to him.

The reason the warranty is mentionad at all is because many people read these posts. Hundreds that are not even signed up as members. I for one, do not want them reading about a mod and think that it sounds great without them also knowing that there could be repercussions. Full knowledge is what you are doing and what it may lead to is very important when doing any mod. I'm not anti mod in any way as I have done the Gotts mod and had a tuner on 2005, 5.4 since 31,000 miles. I waited till the warranty was about to expire.
