Thanks for the helpful information on this issue. I found this article, hope it helps. Had been fighting this issue for a while.
Now find your engine model number on TCM SID97‑3 and verify your unmetered fuel pressures are within limits at idle and at full manifold pres*sure. Let's talk about the term "within limits". I have found that on the TSIO‑360‑GB and ‑LB engines, it is best to set the idle pressure right in the middle of the limits, but the full power pressure should be set at the maximum pressure setting. The reason? When the engine gets hot, the metered fuel flows tend to drop causing a lean engine just when you need a richer (cooler) engine. Even if you have a new engine or a recent fuel pump overhaul, don't think you are okay. Never have I seen a TCM or any other overhauled fuel pump set up for maximum pressure at maximum mani*fold pressure.
