    i just re laped my valves and put a new head gasket on. Idles a little rough but i have DSM 450's in it. i have a vafc (had it so im using it) and i have it set to negative 20 percent. If i think right you want it negative because these injectors put out alot more than the stock and dont want that much for what im boosting. Also have a 255 walbro pump. im aiming for 5 psi maybe even 8. Anyways it hesitates alot like its still running short on fuel. any bit of info wil help thanks... sorry bout the typo int the title

    the 450s are too much for just 5 - 8 lbs

    try prelude injectors - 270s with AFC set the right way

    you cant just play with that, its function is to fine tune the air flow
