Intake/exhaust mods-to map or not?

[Hakosuka]

So, I got a B18C4 VTI which is bone stock.

I also have a 4-2-1 noname exhaust header and a Skunk2 pro intake manifold laying around.

Now my question is...would I even benefit something from this combo?

So the mods would be:

-Skunk 2 intake manifold

-Probably some sort of a CAI or something

-4-2-1 exhaust header

-55/60mm exhaust

 

The thing that concerns me is the ECU mapping. I would surely need to get it mapped, but that is pretty expensive (450€ with the Neptune chip).

Is the stock ECU capable of learning with these mods? What about the second set of butterflies in the stock intake manifold? How are these things done on our funny engines?

The ECU is capable of relearning a certain amount but to get the best from the Skunk2 inlet you would really want it mapped, as you're aware the P9K ecu is non-mappable so you need either a P28, P30 or P72.

 

The P72 is from the US Integra gsr (also B18C4) and comes with a more aggressive base map than ours but it does need some modding to fit. I'm not sure if the others are plug and play or not but you will probably need to do an IAB delete.
