Message: [QUOTE="Rideracelivemx7, post: 890926, member: 305"] the speedo does bounce a little but only between 37 and 40 it will flutter then its solid everywhere else. I spoke with another member on here yesterday that was having similar issues, he said the best advice was to buy AE then data log when driving and see where its bucking then send to my tuner(s). In all honesty i think the truck is just having an oh chit moment and getting TOO much fuel going down the road and its cutting cylinders at random to slow down fuel delivery. this will buck is at any given speed and any RPM, its only load based when the motor doesnt have enough or just isnt working hard enough. I was reading that mass fuel delivery and desired (or somewheres along them lines) can or will need to be tweaked. My ICP and PW have already been tweaked several times by gearhead as he is well aware of what this is doing. The only time i can get this to stop is when i have enough of a load on the motor IE a hill or pulling at trailer to fuel past and it runs great and has a HUGE amount of usable power. What i dont understand is if the motor really is getting to much fuel wouldnt it haze? ive had the cleanest exhaust ive had in years now [/QUOTE]
