ok, lol. i was originally gonna run the vpc (550 chip) with greddy 720cc's. vpc did not like that so i put in my 550cc which were new and i had flow tested. the car is running extremely lean....to the point that it doesnt even like to start. i then took out vpc put the lexus afm and neo in and the car would not start at all. however it will start with stock afm, less air. when it is running, either with stock afm or vpc, it doesnt want to idle and it seems like its missing when i drive it (just drove it down the street and kept it at reasonable rpm because of lean condition). checked the timing and it seems to be ok.
mods r: built 40 over, ported head, os valves, 272's, a1000 fuel system w/ 1/2in feed line.
im seeing now that the 720cc/vpc problem might be caused by this issue, just dont know wat it is. i know u have to add fuel with my combo but nothing is working, still lean and driving rough- to rough to actually drive the car. any help or input is greatly appreciated, thanks
