I'm looking for some advice on how to disable the TCC at say above 80% TPS... I see in the XDF I have there is a Torque Converter Release/Engage vs TPS table which seems to be triggered off MPH, however the highest I can set it is to 127.5mph. I've seen other threads saying that it may be possible to set it to 255mph but whenever I enter that number in it defaults back to 127.5mph.

I'm using the stock 7060 PCM to control a 4L80E trans, however its powered by a blown big block 540 at the moment, so I'm anticipating I may have a trap speed of >127MPH in the 1/4mi so I'd rather not risk having the TCC lockup under that sort of power.

Any suggestions on how I disable the TCC lockup under a certain threshold (that's above 127mph or >%80 TPS?).. Would setting it to 0 mph disable the TCC at those parameters?
