Hey guys have a question. I am starting to get some excess smoking when starting my '06 6.0L. It does it no matter which tune I am on (SCT) and it also does it on stock tune. Only does it in the morning first start of the day and clears up rather quickly (5-10sec) but it does run rough like an injector is not operating correctly, no codes. I suspect I am developing a stiction issue on one or more of my injectors. I am less than 2000mi since my last oil change and I added no additives in that change (used T4). Can I still add 8oz of RevX or another additive this far into the oil change and still have it give me results? What is the best additive for 6.0s? I have heard good things about RevX. Also would a little Seafoam in the fuel help me out here?
