Message Hey guys had a quick question, Im currently running a 10.8 AFR late in the RPM range once boost is fully built on one of my Zemulator tunes. Would you guys recommend leaning it out to 11.5 even if the enrichement in the ZEM cells are already at 51%. I've gone as low as 49% and had an AFR of 10.9. Cant seem to get to the 11.5, can it be my AEM Wideband

Also, when running race fuel, whats a good timing figure to set the ZEM at? 22 degrees?

any help appreciated.

Mark

Best run 12.3 @115 and worst run 12.5 @114 both on a weird tune that would bog in 3rd but thats fixed already. Trying to break into 11's this Friday so any help would be greatly appreciated.
