I reset my ecu to reset thr fuel trims, drove around 2 days about 10% lean after 80 miles, so i've reset the ecu again, swiyched the uprev tune back to the stock map and see what that days after another 80 miles.

I'm beginning to wonder if i had octane boost in the tank during my last tune because i had bought like a 48 pack of octane boost last year but didnt use during winter. Thats the only thing i can think... oh well... new tune soon i guess

I recorded a few pulls to see what the AFR is now snd its much better in the 12s at WOT but the long term trims indicate still about 9% lean. Im confused but feel better about AFR now at WOT.

This is on tuned map so ill just monitor it closely for a bit.

Here's vid showing safer AFR.
