Just had a few questions about my afr, well first of all my car was tuned with your typical 3rd gear pulls. I notice on my wideband when doing 3rd gear pulls my afr's are 11.5- 11.6, then 4th 10.9- 11.2, and then finally hit 10.5 or lower when in 5th gear. Is this normal? Does it do this because of the meth? The afr's I posted are when temps are between 30-40 degrees, they lean out a little as the temps drop. It doesn't really bother me so much in the fall or winter but when summer comes around it runs real rich in 5th gear at wot. Can the afr be tuned per gear, I never heard of doing 5th gear pulls? I have always felt that my car doesn't make the power that other peoples cars make with similar mods, look at my sig. Sorry for all the questions, just want to know more about tuning. If anybody has any info I would like to hear from you.


Thanks

Sounds like lean spool is enabled. You could either adjust it to make it not richen up so much in higher gears, or simply disable it all-together. Note that you'll most likely need to retune your fuel map if you go with option 2.
