I got your tune back in November and installed it and then took my Gt500 in to a dyno in Dallas. The results were pretty low. I have a Question concerning the pulls. What gear should the car be in for the final part of the pull. I would think it needs to be in a gear where the engine is still really pulling hard. If the pull was done in 5th or 6th gear instead of 3rd or 4th gear would there be a difference in the H/p and Torque results.I have been thinking about the results of my pulls and wondering if that could have been a problem. Thanks Gordon.

Hey Gordon, pulls should be done in the 1:1 gear, which is 4th on your transmission. 5th or 6th would show much lower #s.
