[QUOTE="WhiTriCobra, post: 15561196, member: 77590"] Heard the same about DI just a few years ago and they still have bad carbon build up issues. The problem isn't new either. the intake valve goes into the combustion chamber, whether it is port fuel injected or direct injected. When it does, even though it's fast, the valve is exposed to combustion byproducts that can or will stick to it. If the previous combustion cycle was less than optimal, the intake valve is exposed and carbon will build up. Now maybe with even newer technology, maybe Ford finally (after how many years) found a way that will actually reduce it. But I would continue to use known gas stations (better cleaners in the gas) and change your plugs regularly (though they might still work, their efficiency is less and then there's unburnt gas). With that and the higher compression, have they said what the power will be now for the 18's? Maybe 450HP. Guess I could google and check. [/QUOTE]
