2014 Civic SI throws lean code

Recently I installed reflashed my ecu using the preset calibrations that the hondata has for Short Ram intake, Cat Delete and Catback exhaust, since then it has been throwing a check emissions system warning, I've checked the codes on a reader and all of them claim the car is running lean.

Is there anything I can provide to get some assistance with this? like a datalog or the tune file?

Anything helps,
Thank you!

You can post the calibration and datalog showing the issue so it can be looked at.

Here you guys go, sorry for the kind of strange names of the files.

You are running very lean. It looks like you may need some custom tuning for the parts you are using.

Any ideas of what i could adjust to mitigate it running lean?
I dont have the money to be able to run out and get it tuned by someone else so I am relying on myself and forums for advice

You will need to add fuel to the areas it is running lean.

There is in for in the help file about this: https://hondata.com/help/flashpro/fuel_tuning.htm
There are additional topics under this in the left side.
