I just finished testing my '87, and originally was citing the '79 specs that you have and figured I was OK. Then someone supplied me w/ different specs for like '86 and up.

You're aiming for system pressure of 6.9-7.1, with a high of 7.4 IIRC. I set mine to 7.0-7.1 ish. Reading the AFR thread a few days ago someone suggested going as high as 7.4 to find fuel in higher rev's, but others suggest that you're reaching the point of diminishing returns as the fuel pump cannot provide enough flow for that high pressure.

Regardless, play w/ the shims and bump it up to 7 or so.

What is your start issue? Hot? Cold? What's it doing / not doing specifically? I just replaced my accumulator and it decidedly cured my hard hot-start issue, as well as no longer 'sputters to a start' on 3/4/5/6 cylinders.
