I think you literally need to tell your tuner you need a 'go fast' tune. Stuff he's been doing lately isn't cutting it. From the dyno graph you posted, your truck needs RPM to make power, which is understandable considering your mods. He knows this because he dyno tuned it lol. So locking up the converter, you're trapping in the 4000rpm range...not such a good idea.

It's a performabuilt billet 3400, but my tuner has it set right now, that as soon as I hit 3rd it is locking, and my rpms fall off and my truck is just falling on it's face
