I have a 40 Plymouth that I put a 5.3/4l60 into with a comp cams 54-454-11 cam and a card style maf (ls3) im trying to get it started but it seems to be super lean at idle and I cant seem to fatten it up. im a total rookie, what parameters should I weak just to get it to a rich idle kind of situation? heres the tune I tweaked a bit last night bumped idle to 850 messed with timing a bit pulled codes and stuff of course. any help is of course much appreciated. thank you
