Message: [QUOTE="vr6dub, post: 948665, member: 8023"] Sooo, I have a strange issue. When I'm on the freeway doing 65 and I floor it, it never downshifts and stays in 5tc and slowly accelerates while kicking out a smoky trail, never cleans up. Will only downshift when I slow to 50-55 then it seems fine, I guess. Boost never gets over 44 no matter how I roll into the throttle, slowly or fast, up hill or on level surface. Defuel for boost is set for 50.Things I know is no boost leaks, boots are good, no turbo issues, VGT works as it should, intercooler is not full of oil, no codes, dealership has gone through it mechanically and cant find anything, and the last repair being a bedplate seal replacement. Truck has the normal deletes, No Limit Intake + CAC with egr deletes, mini-max with custom tunes. Never noticed it with the stock HD tunes but also never really experimented with the stock tunes either. Is it possible its a tuning issue and if so who all is tuning for the H&S? I know not to go with KEM, so that's outta the question. Any thoughts about it being mechanical with the truck I might not know about or Ford might have missed? So what do you guys think? Any help is greatly appreciated. :( [/QUOTE]
