cruising speeds with SAFCII
 

im having a little problem with maintaining highway speeds or roads with a 45-50 mph speed limit. the AFR bounces from mid 14's-high 15's. if i maintain a speed of 40mph afr reads 12.3(no problem there).

yesterday evening took the car out on some back roads, with a friend to check the afr on the entire rpm band and it runs a near good 13.5 throughout (WOT). messing with the hi & lo throttle percentage hasnt helped at all really. any advice would help thanks!
