I have just started to mod and tune my 87 using TURBOLINK. I know all the theory behind what I'm doing just have no experience. I seem t get different boost levels once in a while, cant zero in on what I'm doing. So I cant get a handle on how many turns does what. And also what kind of O2 mv changes can I expect from fuel pressure changes. I just started tuning today, basically. I just put in a WALBRO 307, and hot wire, Thrasher 92, with sunoco 94. I had a faulty stock pump I guess, was pinging with stock actuator and the chip. The hot wire and and pump solved that. Then I put on the adjustable rod, first test hit 22.9 psi, turned the hell out of it, still get 21, now its almost as long as the stocker, and its still 17-19. And turning up the FP doesnt seem to do much. I'm getting it settled now, but what boost levels can I expect from stock injectors, and only 94 octane? STill get knock once in a while, but for most part, I am getting good mv's and very low KR around 17 psi.
