Alright Im getting tired of 8-10 mpg on my car on stock boost. And need some info about setting my SAFC for cruise and for boost.

currently i got the settings on
low/high
15/20 for all Rpms
low throttle im seeing around 13.5-15.9 afr
boost im seeing 10.9-13.5

My current set up is:
MBC, 3 inch DP to straight pipe to stock exhaust, Boost Controller, AEM UEGO Wideband and SAFC I.

My question is:

- during idle what kind of afr's do i want?
- during 30 or less throttle what kind of fuel corrections are needed and what kind of afr's do i want to see while not in boost at all rpms?
- at boost which is around 47% throttle what kind of Fuel corrections or afrs should i see while in boost.
- and what throttle setting % do people usually set it on using Map sensor as throttle. (hi and lo)

Thanks
