I finally got to test it out this past weekend at our local 1/8 mi track that had just reopened since last fall. They laid down new concrete and new asphalt. It was hot, humid and above 3000 ft air all day. This was my first time out since last fall. I started out with last years tune except I installed a set of Dynomax bullets behind the headers. My first shake down pass netted me a 1.69 60' and a 7.99@85.55. After some tweaking and a few more passes, I brought her down to a 1.65 60' and a 7.89@87.71. I then opened up the bottle and the first pass brought a 1.61 60' and a 7.63@90.54. I'm starting to like that cold air in a bottle.
