that is possible
what are you basing your "consistent AF ratio" on? i hope its not the colored gauge. get a wideband, they arent 'that' much money. if your running boost you should check out
www.pgmfi.org they are a tuning forum that i spend alot of time learning on...i think you will discover alot of useful info.
do u have any slips for this car? curious as to what its running.
