    IAT is also pretty high and climbing during a pull. Since this is a swap I'll bet the filter is somewhere were it's getting more engine/radiator air than outside. This will cost huge in performance.

    The convertor locks in first gear early and then stays locked though the whole pull at 16:26:18 to 16:26:24, that combined with pretty much all things mentioned above will make it feel like an absolute turd.

    Whoever did the lock up tuning, lose their number...

    These guys are very good tuners. But you have to do what they say and answer their questions for them to even begin to try and help you.
