I just got finished hooking up my HKS EVC V (Black-KPa)

I was confused and set my warn to 158 (about 23 psi) and I tryed to dial in my boost to 22-23, with the knob all the way down I was only holding 15 so about half way I hit about 21. I turned it just a little more and when I hit 22 PSI my car shuttered, kind of like I hit the brakes. Is that the warning? From what I read its just supposed to beep.

I've read 10 threads about this and I dont really see my answer.

any help would be nice

all warmed up, 3rd gear pull from about 40mph
EDIT: went out again, I was thinking fuel cut, I have a walbro in my room, (I know its not helping anything in there) I was goin to put in this weekend and I will finally be getting my laptop this weekend and getting a tune from 4 wheel slide

more info the car held 20-21 up until about 48-5200 RPM

Still sound like fuel? I hope so I'm running on my low setting at 17-18 PSI until my tune and fuel pump are in.

thanks

was you car all warmed up when this happened?

 

yes all warmed up, 3rd gear pull from about 40mph

 

i just a hallman pro installed on my car, i had a problem with that instant shutter, backfire or whatever you want to call it. i use to get a po234 code, which was an overboost which is maybe what you got when you have no tune or hose incorrect. i set my boost at 19.5 and it holds strong and no more problems.

 

bump for more info.

one night I spiked 24 before I even did this controller and it never did this "shutter"

I'm going to mess with it more today

cheers

 

do you have a tune? it may be your boost cut

 

Sounds like fuel cut.
