hello everyone,
i'm new to tuning have no clue where to start but do have the equipment to burn and erase chips.
i have been having a problem with my truck running too rich,
what i have is a 89 s10 4X4 with a 88 5.7 running headers, heated o2 sensor, 700r4 from a full size truck(speedo off a little).1227477 ECM with ARJT eprom that i burned today, was running eprom AMUR but ARJT seemed a better fit for what i have.
fuel pressure holds steady at 13 psi, just rebuilt TBI(new o-rings, gaskets, filter screens) doing a test run today everything seemed ok except for the BLM it stayed around 108 for most of the run.
i have attached my log from todays run.
any advice would be appreciated
