Im in search of a regulator spring for the stock tbi regulator that has been made adjustable. After doing math, it would be ideal if i could get a spring in the 20-30 psi range. The guy at tbi chips states he has a spring that will do 12-40 psi in the stock regulator with a fuel pump that will support it. This sounds to good to be true when every other spring I see varies by about 5psi. If it is possible then I will buy it, but I have heard some not so great stories about him so im a bit weary. Here is the link.
