Hi guys, I did search the forum but couldn't find my answer.

I just installed my new IPD 74mm Plenum and IPD Highflow Y-Pipe and wanted to know if there was a "Learning process" for the ECU to calibrate and adjust the air/fuel ratio and other data.

I went for a cruise and noticed the car made 14 PSI of boost and used to hit 16-17 before the mods. I checked the Y-Pipe coupler and everything else, there are no boost leak.

Outisde temperature is 55F, perfect weather for boosting.

Any idea?

 

Question is? Is the car faster after the mods? Not sure if i am ready to tackle the airflow science yet. Has the sound of the engine changed?

 

yeah it feels a bit stronger, engine sound is pretty much the same.

 

These are additions known to produce limited gains. The plenum has been claimed by many to be a waste of money. I'll be curious to hear the feedback you get from others. Are these in addition to a tune and exhaust? Without those, the gains would probably be very limited.

 

If you really want to speed up any learning, disconnect the battery for 5 to 10 minutes, and then go for a drive.
