Can the sct tuner adjust my stall speed. I'm running stock auto tranny with stock converter I was reading some posts and ran across one that said he adjusted the stall speed. If so would that allow me not to buy a new torque converter?

 

No... No tuner is going to be able to do that... The Torque Converter Lockup can be adjusted. (though you will probably need to talk to your tuner...) In the old extreme tune software there was a section for lockup....

 

+1, lockup only I believe.

 

Can someone explain what the lock-up is and what it does?

it's a good read

 

your tourqe converter goes into lockup in fourth and fifth gearduring part throttle and eliminates slippage of your tourqe converter by going into the lockup mode and helps increase fuel mileage by being basically like a direct drive like a manual trans would be
