Thanks I may take you up on that offer. I know I want to run gas for warm up and shut down. The 904 has a tranzact brake, and we just had it updated to low band apply cuz it was an early unit. Running an 8" ATI. It was set up for the 4.86's but the car only slows down .05 with 4:30's. The car actually belongs to a customer, I built the engine and did some other updates on several years ago. He doesn't want to drive it after he saw it run hard!
