[QUOTE="TD-5, post: 804495, member: 12311"] Comparing the stock file tables to the tuned file tables, they have made changes from the mid torque area & 1600 rpm up. I took the tuned files & reduced everthing by 50% for a trial run. The truck was less responsive off idle & at low loads, It smoked more in this area also because the back pressure wasn't there to spool up the turbo.. Once the revs & load were up it didn't feel much different. There may be some room for small movements in that area from mid torque/mid rpm up, but whether that would translate into positive improvements in performance or efficiency..... ??? Without a WHOLE bunch of long term testing its all just seat of the pants. At the end of the day I'm back on the tuned files. [/QUOTE]
