A/F Ratios Seem all over the place

Good Evening Everyone!!

I just did a run in 4th gear WOT and It looks like my A/F ratios are all over the place. I just installed a Ford Focus ST intake manifold and something seems off. Can someone take a look at the data for me and let me know there opinion?

You going wot at 2200rpm? Brave soul.

Afrs seem around the mid 11s and fairly consistent. Your ltft before pull is -7.81 which tells me you have a small leak somewhere which is probably worth looking into soon.

Did you retune? Because going from OEM manifold to st is a pretty significant change in flow and probably needs a touch up

If you've done a boost leak check, checked plugs and ensured gap, cleaned maf then I'd say tune related imo.

I see your tuner is drama....have you talked to him? Although around here he gets no love

afr fucked up? Your tuner would tell you that what makes him better than the other tuners
