I have the same question. Hopefully, someone will chime in and help us out. In other words, if you install, say a 3400 rpm stall 2.1 STR TC, can you tune it instead of installing a shift kit.
Thanks!
After having both tuning for increased line pressure, then installing a shift kit, I'm can't see how tuning could effectively ever do what a shift kit does.
The shift kit has you drill a number of holes in the separator plate where transmission fluid flows throughout the case and valve body. In addition, certain valves are replaced. Both of these mechanical changes allow more fluid to flow, at a higher rate, and increase pressure and allow for firmer, quicker shifts.
I don't see how electronically increasing line pressure can overcome the physical limitations of smaller holes and smaller boost valves. I just don't see it happening. Perhaps turning up line pressure can give you a little more advantage than stock, but you would necessarily come up against the physical limitations pretty quickly.
What is the result of installing a shift kit? Faster shifts? Harder shifts?
