I let my Ecoboost go because of the oil dilution problems. I let the dealer try the TSB fix, but it didn't fix the oil dilution problem and by reading of how EB owners are now worried about stretched timing chains with low miles, I didn't want to be a guinea pig anymore and went back to basics with the 6.2L. I enjoyed driving the EB and it pulls hard, but I'm also impressed with the 6.2L and want to boost it up the performance of the motor, but worried about the tunes and etc. With your installation of headers by the dealer without the tune is refreshing to know and I will probably do the same within the next few months. Thanks again for the information.

Hey bud. I took delivery of the truck in Jan. of '11. It was Nov.- Dec. when I bought the Stainless Works system. The dealership were I ordered the truck did the install. It's been nearly 2 1/2 years and no issues, leaks, squeeks since then. No, I didn't have to have the trucks computer redone. The performance increase was immediate, and awesome! It really didn't start coming alive until a few days later. I could feel the performance getting better and shifting better each day. I guess it relearns on it's own. I take the truck to the dealer for oil changes. I have Free Oil Changes for as long as I own the truck. Sorry I can't help you there. Why did you let the Ecoboost go? I ordered my Lariat in Oct. '10. I never even thought about the Ecoboost. When I learned that the 6.2 would be available in other F150's besides the Raptor, the 6.2 was a Must Have on the special order ticket. I know your gonna enjoy your truck, even in stock form she's a beast......
