Once again I am a budget racer and there’s no way in heck am I going to buy 8 O2’s or 8 EKG’s. My single O2 had me printing time slips on 93 BP pump gas and my single EKG printed 5 passes over two days from a 6.078 to a 6.091 and the only reason that pass was so far off is because it wheelies way to high and I came down a hair out of the groove and had to bring it back.
