You likely feel a leaner mixture in open loop which is bad as the knock sensor stops working at high throttle.

Until you get well over 300WHP, and even then it is questionable, the stock intake is fine and flows better than the engine needs and most importantly, that flow is what the ECU is calibrated to!

Unless you have a tune with a map specific to that intake, you should not change intakes. On a MAF car, they and their corresponding map are critical to basic engine function.

It took many hours of logging to get my intake map remotely close to accurate compared to the stocker.
