Thoughts? Its seems to be shifting just fine... hits all the gears. Downshift from I think 3-2 seems hard, but not bad besides that. The trans is still learning also because harder throttle it shifts a little harder, and defuels kinda bad, but I need to fix that in the tune. Thanks in advance. -Travis
