Hey guys, need some help. Im running Idaho robs big tune which is GREAT but hauling a trailer or pulling a big hill it smokes like a freight train at around 50-60% throttle at around 1700rpm. i think its way over fueling but it works awesome unloaded. i tried increasing boost in that area with no success but i dont want to ruin tune. I tried to contact rob but he must be busy. Where should i start??
