    Believe COT is Cat Over Temperature protection - Adds fuel to cool the cats during WOT?

    Do I want to disable this for performance or keep it in the on mode?

    Still not absolutely positive on what COT means, if I'm correct logic says don't worry about it with gutted cats - but might affect other tables? I'd ask whoever is doing your tune.

    All I have is a Diablosport tuner and was playing with my st/lt trim!! My left bank keeps spiking up -32 to -38 to-12 to -2 to back up to -28!! Keeps going up and down and cant stabilize it. This of course being my LT trim!! One thing that I believe it has to be is that I do have an exhaust leak at the manifold/ converter point!! 1 stud is broken and is leaking pretty bad! Think its sucking in fresh air and leaning it up only for the computer to fatten up the trim!!

    An exhaust leak near an 02 sensor will definitely throw things off - should throw a code though?

    Catalytic Over Temperature. if the cats get too hot, the computer throws a bunch of fuel at them to cool them down. if you have no cats, then disable it.

    do you still have rear o2s? if not, then see if you can delete those codes. i see you are in kissimmee. if you want, we can meet up and discuss things.
