I haven't had the chance to Run it yet...I put it in the car and started it on the bench and gave it a quicky tune...seems like it moves smoother through the power band and it came in a lot quicker...I only wanted to see how it would work and put everything together right...I took it back out and am tearing the rest of the car apart now...was my basic intention to tear it all down, seal things up and inspect things while I was at it...It's just coming along slowly due to time constraints.
