Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

please dont tell me this is knock



i need a scanner but the ol lady is getting mad at me for spending money on the car, even though this is the first pay check in like 2 months that ive spent some money on my car, fvcking whiny ass
 
42 psi idle with vacuum at the regulator. 58ish with no vacuum. Drop it down. You might want to double check the gauge is working correct. Thats a CHit ton of pressure you have. I say the chugging your seeing when in boost is caused by this. Higher pressure=lower IPW's the injectors are opening shorter but over fueling

Holy if my gauge is correct then yea no wonder my car is about to die. If its faulty what would be a good idea how to check?
 
Ok i tried lowering my fuel psi. I got it to the mid/upper 60s, anything lower and the car struggles to idle and the rpm's go from 700-1500ish. Or is that normal, ive heard that the ssm90 sometimes does that when its cold, or is the psi gauge faulty and i am at the right psi?
 


Let the car warm up then lower the FP. If it stalls then your gauge is off. SSm90's do indeed surge on a cold start. So do must modded gp's FWIW
 
Ok thanks. Yea i did notice the idle improving once it was starting to warm up. Il give it another shot tomorow
