Stock boost cut/fuel cut, when?

Alright, i have a VF22, downpipe, intake, cat-back, up-pipe, fuel pump, Sti injectors, and Profec B.

My question is this: When does the stock ECU fuel/boost cut come in?

I have yet to install the injectors and Profec B, but I want to turn the boost up to 15psi or so. I think that I am going to run into the stock ECU's boost/fuel cut. Am I correct?

The factory boost cut/fuel cut is at 18psi. just my 0.02 cents but i wouldn't turn up the boost that high w/o engine management hell i wouldn't have put any of that stuff on my car w/o it man. but i can understand your anticipation of having new parts. but i would really look into getting at least a unichip maybe a Link or a reflash or something before u go and think about turning up the boost. but thats just my 0.02cents good luck to you

18psi one one turbo is not the same as 18psi on another turbo.

Without engine managment, I wouldn't go over 12psi to be on the safe side.

Ooo...you're just the guy I've been looking for.

I have a Vishnu Stage2 EcuTek that I need to sell. It is mapped for a vf22, larger tmic, Sti injectors, fuel pump, up-pipe, and turbo-back. Boost is set at 17psi.

Please tell me you have a 02WRX 5mt and that you're looking for a deal like this to knock on your door.

You'll be my newest best friend if you do.
