Just got back from my in person tune with CZIPAR Performance with the 6.0.
So far it's GREAT! Did a mild, tow tune, nothing crazy. The shifting is excellent now. No more lagging or gear hunting. It keeps momentum up with very little effort from gas pedal now. It drops a gear when it needs to, very smooth and crisp. Going to test it with 8,000 load tomorrow. I can't say i feel more power.. Just the power is delivered much better to use the POWER! Very happy so far! GET YOUR truck Custom TUNED!
