i have a 94 that i took the plate out replaced the cup washer with a flat one, ground an 1/8 in off the foot and smoke screw half way out and adjusted for full fuel at 20 psi. i need some opinions on this work? i only have intake and exhaust no turbo or inj. it really opened this truck up bein a 5spd with 4.10s:thumbsup: my real ? is can i adj for full fuel even lower psi w/o drownin my turbo out since its stock inj. and fuel screw all the way out? or binding the spring in the afc? i also need 4k springs cheapest place to get em? and yes i just wont float my valves by overrevving past 3200? cuz i dont plan on 60 lb valve springs quite yet. I appreciate any expert advice!!!!! o i almost forgot which way can you slide the hole afc housing and what does that gain cuz i notched it so it was the same the first time.

afc full forward = max fuel
afc towards firewall = least fuel

afc adjust pre boost fuell

you wont have a problem running max fuel with stock injectors for the stock turbo.

if you want to max out your truck now....plug your wastegate, or use a boost elbow, afc full forwad with #10 plate, afc adjusted for the amount of smoke you want. once you do all that a pyro gauge is a must.....

oh and be ready to put an aftermarket clutch in soon after that.
