Your time slips dont have relevance to my comment... I mentioned power up top and your posting time slips. Your slips dont show power...
Actually you were sort of arguing. Lol. You suggested he may have not been using the proper fuel, or that he may have been playing with the jb4 settings and fudged things up, or even that he may have had a bad jb4.
The slips don't show power? Maybe not actual numbers, but how else do explain, if not more power, such higher trap speeds on the same car, same track, similar da?
