2018 SS, most mods listed. I swapped the in-tank fuel pump with a ZL1 unit the other day. The car runs fine but I can't seem to get a straight answer on any modifications I need to do to the tune to take advantage of the new pump. I found a couple of links but it wasn't very detailed and the settings listed for the table ECM 6975 were very different from mine - his started at like 80 and moved down to 70 with flow rate. Mine go from 550 to 503. That doesn't match at all. So I guess I am asking, what do I need to modify in the tune to make this pump do the best it can? Thanks everyone!
