After Apexi Dp Install

[STGGSX]

I just put on my apexi down pipe, with no cat, and now the car seams not to idle as well as it did witha stock dp on. I have a greddy informeter and its idleing at 710 to 740, is this right, is my car just getting use to no cat, is it learning a new fuel curve, i dont know can anyone help me. or is this ok.

My car did the same thing. Its normal. Its because you dont have any back preassure. Watch your boost also It will jump up a little bit and you might start hitting fuel cut.

You should at least back out the idle screw a bit to bring it up between 900-1000, to bring you back to that normal feeling idle, if that is what you prefer..
