Message: [QUOTE="m_j, post: 1402156, member: 25646"] factory tunes in a 7.3 do not pull at 1800rpm so why would a modified one? any idiot trying to get better fuel economy with low rpm while climbing a hill doesnt have a sniff anyway. low rpm is for flatland cruising, pulling a hill is time for power and that is far easier on the motor at the upper end of the tach. get up the hill as efficiently as possible in the shortest time. when I was a company driver for a fleet I would beat low rpm drivers in both trip time and burn as much as 100litres of fuel less then the guys that pulled the n14s down to 1400rpm before downshifting.I keep the rpm 1700 -2100 up the big hills. all trucks were governed at 104km/h loaded at 104500# running the fraser canyon up and the coquihalla back the higher the HP rating the less fuel I burned. low rpm and low power do not make for better fuel economy in my experience. keep the EGT gauge happy [/QUOTE]
