1jt: A dyno tune, done correctly, is second to none. A good tuner will get the most power from your truck, safely. There is always a tad more power left under the table, for safety's sake. If you want a Superchips Custom MicroTuner, I have them available and can write a decent program, given the additions to your truck. I will still tell you that a dyno tune is better, I will tune it very safe, I can't put your truck on the dyno and read a wideband O2 analyzer, so it will be tuned very safe.
