a bit confusing those 2 latest replies.
So if I connect this DOHC regulator and then drive it while keeping the boost lower than 0 psi it will be ok? I do have a small band AFR gauge in my car to monitor the closed loop function.
That way I can take a short drive and see if it goes overfuelling with another regulator.
it will show if your reg is no good. As for rising rate i dont remember turbo technics changing the fuel reg when they tweeked the dohc 8v.
Also i am sure i used a dohc one on a fez turbo.
