Brian Tuten's EFI Renegade coupe was off-pace at Columbus, and he wasn't sure why. He spent the majority of the weekend scratching his head as to why the car wouldn't run the number. He was able to squeak by Chris Van Gilder in Round 1 with an 8.80, but we've seen his car run 8.40s in competition so it was a puzzling situation. Brian said before the event he swapped to a different cylinder head with a larger intake port, so he thought port velocity might've been compromised. Bad thing was he didn't have the previous heads with him at Columbus to test that theory before his Round 2 match-up against Larry Hourcle, which didn't end well for Brian.
