Sure enough, I just got back and the truck runs smooth a silk. Motor just hummmmssss along. Some smoke from the pipes but its not broken in yet. I had set the tps at 1.01 but it changed to .98 and shifted early causing lugging. So I just reset it for 1.02. I'm letting things cool down and watching to coolant recovery tank do its job. Monday I'll have more miles on it and get it timed. It starts without grinding and never stumbles like I have an air leak but I do see number 6 return line cap leaking some but not all the time. I will probably repair that before I have it timed. Never know whats leaking there.
