Yep you need to hook up somehow. That thin air is killing you. I haven't had any times on my blue coupe yet. Still finishing it. The old black roadster ended at 12.1 1.76 60 ft. 115 mph before she went back into retirement Sunday car only. Lol. The coupe is all but ready. Need to finish some wiring so can data log then last mod Is to install the meth kit and retune for it.
