Leaned out Hondata tune 15%

I leaned out my +6 PSI I and JEN tune and the car is super fast. I am a little confused about the fuel readings can somebody please advise me on what is stoichiometric what's lean and what is Rich? Thank you. I kept seeing 10 to 1 with wide-open throttle so I kept leaning it out but I think I have something wrong. It's too fast to be true. The spark plugs do not show that it is running lean.

post your calibration and datalogs

how are you leaning it out? are you adjusting your AFM?

If you don't know what you're doing you shouldn't mess with it... Stoichiometric is 14.7:1 which means 14.7 parts air to 1 part fuel.. this is considered perfect ideal mixture for a NA engine.... Since we have a turbo you don't want to run 14.7:1 under boost or you will blow the engine... Honda plays it safe and targets slightly rich at 10:1 under boost which is what you're seeing at WOT.

10.0:1 is way too rich. you might misfire running it that rich.
factory WOT is around 10.89:1

Brave soul playing with things you have no idea about...

Can I have your back bumper after your engine dies?

If your knock control is staying low. You're mostlikly good to lean it out a bit. But I would do it slowly so you know when knock control starts to hate it. I think ktuner has WOT enrichment ending with 11. That seems lean enough for me tho.
