I am useing a MPS auto shift, havent gotten back to the strip yet. Also installed a innovate data logger, i was running very lean. My last 60 was a easy 1.70 slipping the clutch leaving at 8500 rpm. Shut it off before the rev limiter in first. ( couldnt get it to shift out of low gear) auto shift was wired wrong. still ran a 7.82 at 65 mph in the 1/8.
