So if I put the Fabspeed intake on my car along with the side muffler by pass pipses I have will it cause the car to run too lean or will the stock ECU adjust and run too rich?

I hear tha the stock ECU is running rich but then I hear this new stock ECU will adjust to a lot of mods...lots of confusing info out there on the new 09 997.

thanks!
