ive never been good on a .4 tree, gotten use to the .5 tree. Well your times are abou .6 faster then what i was able to run last week in grand junction at our dragway. I had some traction issues, but was suprised she didnt run quicker myself. Did you have any hook up issues? or did she just scoot? Im thinking i may have to invest in a sprint booster like i did for the na, seemed to make a difference in launch capabilites
