Just installed my evolution yesterday. It runs great but has a bit of a serdge in shifting in all programs.i was told that this would go away after time. I run level one most of the time but had to try level three and ran a 7.3 0-60 time with spin. I thought that was quick for a big truck. The truck has tremedous torque off the line but then slows and serdges into second? and then takes off again. Has anyone had this issue? is the program designed like this to lower egts before shifting to next gear?
