Mine too
I havent used any other tune on my truck but LV3/93 oct. I do not have any other tunes and the only thing my 2008 SCrew 5.4 has is a flowaster 50 Cat Back single side exhaust. EVERYTIME I drive it sounds like I am misfiring, or its not getting enough gas/bad gas. My truck only has 8000 miles on it. Most of the time driving around my town I am under 35mph. I live on Long Island less than 100ft above sea level and rarely have I gone more than 200 feet above sea level. The only time the sputtering stops is when i am getting on it (1/2 throttle or more) or when i really get on it WOT on the highway.
Sometimes I use the throttle position gauge and the majority of the sputtering happens under 15% and at slower speeds. When in stock mode there is a delay in throttle response under 15% so its lose lose - damned if i do damned if i dont. The sputtering doesnt really bother me but the fact that it happens enough that my wife notices it begs me to ask the question/or suggest they have/will a fix for it?
