I was getting 28 psi boost from the "370" software so I needed ...
58 + 28 = 86 psi minimum. The pump was only putting out 83 psi under simulated conditions (engine off but with 28 psi applied to the 4 Bar pressure regulator). As a result, I was leaning out under WOT boost. Relaying the pump to the battery helped.
Use search for the procedure/write-up about last August 8th (2004).

ce crez de asta? ar fi pompa de vina? ma gindeam sa incerc alt chip dar nu cred ca chip-ul e de vina. hmmm am schimbat si filtru de benzina, injectoarele, burjiile, si nu mai stiu cite alte. trebuie sa controlez ce volt primesc la pompa. bine, trimite-m si mie un semn de viata. ciao.
