PMAS vs Gen3 airbox

[ice445]

So a quick play around tonight produced this :

And at idle, this was typical :

DA was just under 500ft.

So can someone decipher that for me (in layman’s terms lol) ?

Ignoring the calculated power value, does everything look OK, and does that give me a good baseline for testing possible future mods for improvements ?

Cheers,

Exactly how my car reads on the stock tune except I'm at 4300ft elevation, haha. I'm pretty sure it's normal on a gen 3.

It's pulling fuel. The ECU thinks it's getting more air than it is. Hence pulling fuel. The engine is getting less air than what the sensor is telling it.

Which makes sense if the air is now laminar with it being turbulent before.
I would assume as engine speed increases the miss-match will get smaller.

Not necessarily, the closed loop control on these is quite advanced. It's not like the cars of 20 years ago. I find it hard to believe brand new cars are gonna be incorrectly reading the amount of incoming air. I don't know what, but the stock tune is definitely doing something there since my long term trims look exactly the same as WD's.

I think the stock "in the green" is 10%
