Thanks. I think that the RPM Decay was set at factory default which might not work for everybody's engine. The Deceleration Fuel Cutoff (DFCO) is supposed to cut off the fuel during deceleration to save fuel. I think the setting is set up for a automatic car and not a automatic that has a manual valve body that coasts in first and third gear (same for an manual transmission). They say that the deceleration fuel cutoff should be around 16 and the deceleration fuel return should be around 18 for a manual transmission vehicle. I just raised the temperature that the DFCO comes in at from 68° to 300° effectively turning it off. I am more worried about performance than gas mileage.
