[QUOTE="Sterling6.7, post: 1433773, member: 17432"] Well worth the change from GH to Tyrant for me. The power was always great but the shifting kept getting worse over time and Mike helped me into the new tunes. The power is down a little, less smoke but shifts flawlessly and is exactly what I am looking for. Sure, more power is always nice, but I am always shifting and rarely need all the power. I have been thinking about trying the GH engine tune and the Tyrant trans tune to see what happens but I really don't want to screw up a good thing in pursuit of something better. [/QUOTE]
