How do you do the relearn with out trucks and LS swaps? I read on that post you linked the ECM has to have a signal from the brake being pressed.

You should have a wire going from the PCM to the brake light switch that deactivates your torque converter lock-up.

Did you get a hold of Brian Tooley today? I really doubt a crank relearn will do much, especially since it's had the tune modified, (I would think that would have been in it? Not sure though) but if you want to try it you can use my scanner. It's pretty easy to do and only takes a couple of minutes.
