Hi, to all on the forum. I'm the freshest newbie.. I have just started working with efi in the last few days. I'm trying to program a 01 ws6 with a build tranny. It has a stall and beefy internals, and it just will not shift worth a crap. I have been in the computer briefly and worked with a few different setting but nothing seems to be fixing the problem. I talked to another guy today that said the factory computer may be to blame. That everything works off voltages and the computer may not be making the changes..Any suggestions would be greatly appreciated..
