I talked to Ion Soltan of MadZ28 who did the tune on my 95 heads & cam Z28. I told him about the problems I have been having with my car breaking up under load, and he said:
This looks more like a plugged cat or an ignition issue, if it's doing this on the 24s. If it's doing this on the 24s specifically after the fuel pump install, you will need an adjustable fuel regulator and set the fuel pressure at 43.5. I still think you have other issues, most likely ignition related.
I obviously ruled out the plugged cat problem since I don't have any cats to begin with.
Currently my ignition consists of a MSD Blaster Coil, Summit Opti, Taylor 8.8mm wires & NGK TR55 plugs (not sure of the gap). I'm going to tackle these issues this week and try swapping out parts mainly the blaster coil. I'm going to wait before I send out the computer again untill I have check the ignition over again. I've had this issue for a few months even back when i first did the heads & cam with the same ignition set up.
Now back to my main issue... a fuel pressure regulator. What exactly does it do, where does it go, how difficult is the install, will I see gains, and is 43.5 sound right?
