Just curious if there are any new options out these days for tuning?
I sent my 411 to Lextech for a basic tune…before I did the pinout or pulled the engine (that had a spun main bearing) out and the truck would start and run enough to limp it around the shop…then I pulled the engine, had it rebuilt, and put it back in… It cranks right up but it’s definitely not right…
I haven’t done anything as far as hooking a scanner etc up to it etc…so no crank relearn…but I don’t understand why my speedometer is like 35-40 mph off when I sent my tire/wheel size info when I sent my ECM off to get flashed and the basic tune…and wondering how to figure out what was or wasn’t changed/deleted???
