Mine will accel like no tomorrow with no issues, I'm thinking the problem with the decel is the system is not taking fuel away quick enough. which is causing it to pop in the exhaust. I will data log it tonight or tomorrow and find out. As for the air fuel 13.8 seems to be the best, I found if I run too lean I can't keep the engine temps down. At 13.8 the truck will idle at just under 180. It took me a good 2 weeks of messing around and talking to people to get the truck to start and idle right.
