[QUOTE="reaper1441, post: 1253634, member: 26658"] Flashed this tune last week and so far have been largely unimpressed. Ebov opens during acceleration at low rpms causing the surge people complain about(their shop truck does this as well), LTFT's are off almost 30%, truck misfires at idle with plugs gapped correctly, tries to stall when putting it in reverse(i drove their shop truck and it does this as well), ACC causes downshifts with a hard thud and the throttle command ratio is far from ideal. I've seen 94% throttle plate at <20% accelerator input. I also appear to be getting significant tip in knock when in 4wd. These problems are with the offroad tune and probably why they don't recommend towing with it since its prone to tip in knock under load which is what im seeing in 4wd off road. I'll be emailing them tonight but i'm working on getting a new tuner lined up with significantly more experience. And I'll be using something other than an inertia dyno. [/QUOTE]
