Going on the rollers tommorow. Have changed the oil and filter and plugs. Will add a couple of bottles of Heet. Running 93 unleaded with cat and functioning egr. Swapping in a 195 stat and fresh PCV valve tonight. I have two chips to choose from, a Reds 93 and the Conley Mini-mag. It's passed with the Conley every year before but I was just wondering if anyone knows if the Reds might be any better on emissions. Running out of time before the Nats and don't want to have to deal with an inspection failure now. Thanks.
