The Holley system will not allow closed loop on the 2 step. Closed loop happens at about 4500 rpm off the two step. My Camaro qualified better than usual in Denver but my Firebird wouldn't run the index today in Super Stock. Not sure if it's broke or I just don't have the tune right. I leaned it to 13.1 from 12.7 after 6000 rpm (per suggestion from Duane Dickens) for last qualifier in the morning so we'll see. Thanks again!
