[lucas isherwood]

i have a small 16g turbo, walbro 255, 550s, 2g maf, hard ic piping, upgraded stock sidemount with larger inlet and outlet, and an intercooler sprayer. im getting an afc on thursday and im wondering how much boost i should run. whats the most boost that you guys would run with this setup? i dont want to just be blowing hot air out the turbo so whats the best psi i should tune the afc for. thanks

i also have stock 1g internals and a metal headgasket with arp head studs.
