Default streetuner + how to tune with intake

so what parameters do we have to adjust to get the most out of an aftermarket intake? i'm looking to ditch the stock airbox soon and install a K&N typhoon.

I have stage 2 accessecu with a Perrin short ram. Works fine, the ECU didn't have a problem learning. Make sure the K&N won't give the ecu weird readings. I looked around a lot and went with the Perrin after I had enough confidence that it won't mess with the maf.

It was my impression the K&N Typhoon wouldn't require adjustment. Once you put it on, you could confirm that by observing A/F Learning (also called Long Term Fuel Trim) to insure they're close to zero.

A general approach for a non-standard intake would be to make adjustments to the MAF calibration table such that the target A/F ratios at various loads in your fuel table agree with actual A/F ratios reported by a wideband A/F sensor.
