stock airbox with k&n drop in

 

Ok, nevermind then. I had an air adaptor that came with a nice aluminum intake pipe, but the adaptor messed up my airflow so much going into the maf sensor, that I was having boost problems, fuel cut, etc..

 

I did a few wot passes last night and 2 this morning and there was no boost creep at all. I dont get it! Why does it do it ocassionally only and not all the time?

 

Possible either Weather conditions or maybe its the gear you are in, or how you are going WOT if you are leaning in then opening it up or are you just stomping the go pedale to the floor and waiting for the boost to build.

 

well i never used to get boost creep b4 the o2 housing install when i hit it at wot, the boost just spiked real quick and droped normally. Now the boost doenst spike as fast, it goes to 1.5 and starts climbing to 1.6 and it holds boost going already in redline!! The car feels fast as hell but it concerns me bc the other day i hit fuel cut bc it was holding boost and i still have the stock bov

 

last night I drive the car again, still have boost creep, put stock air box back in, no luck, boost creep. Today, I swap the stock 02 back, didn't touch any other setting, adjustment or change any other parts....BAAAM no more creep, It's the 02 housing, maybe we just got a bad one where the wastegate port didnt open up big enough to keep up with the exhaust flow. But its definitely the o2 housing.
