Iv been battling this weird issue where afr ramps up to mid to high 12s during wot then back down. I also have the infamous hesitation/backfire after shifting form 2nd to 3rd while at wot. When this occurs afrs ramp up to the 13s right after the hesitation. I’m on e25 and fully tuned my tuner says it’s not the tune and he suspects a sticking bpv however I blocked it off and no change. I pressure tested the system from the maf housing back with 23psi and no leaks. Brand new 02 sensor maf sensor and maf o ring. Brand new spark plugs as well. Here are some logs. Anyone ever seen this before my tuner is convinced it’s a hardware issue nothing to do with the tune and I’m stuck at a loss.
