Torque Converter lock up

Brian are you there? In the latest Tune files I am having acceleration problems at highway speeds. At 70 mph if I punch it to the floor it downshifts and begins to accelerate as usual, then it up shifts then downshifts then upshifts again. It does this several times so I have to just let off the accelerator and not pass. Never had this before with the old predator. Had this problem with Superchips but downloaded that tuner and benched it.

Unrelated but what is KAM? Keep Alive Memory. What happens in a reset of this.

I ran iinto the same problem but is was because my torque converter had a malfuncition and wouldn't hold up to the power, the warmer the vehicle got the worse the problem, try driving it cold and see what it does. This was a brand new out of the box converter with tripledisk lockup, billet front cover and so on.

Last time we spoke I had just got the tuner back upgraded from diablo untested. My line pressure is not a problem. Driving it cold makes no difference. its not the tranny or converter. Had this problem with a Superchips tuner and got rid of it and went back to the Diablo tuner with no problems. this was just before I sent it in for the upgrade. Was trying Superchips because of the Theft System problems I was having with Diablo and no support.
