your being to vague. what setup? engine? at 1K and 2K on the hi and lo throttle i'm at -34% just cuz it idles REALLY good. it might not be for you just play with it. hi throttle i'm at -37 on lo vtec and -35 on hi vtec. on lo throttle -47 on lo vtec and -45 on hi vtec. throttle points are at 20% lo and 65% hi. you need to have the lo at a fast highway cruising speed like 75 mph in fifth gear or any cruising speeds. and the safc will slope the air/fuel ratio up form 20 to 65. do you see? it won't be on lo throttle then instantly dump 10% more fuel on hi throttle. that will happen if you set the throttle points together like 98% lo and 99% hi. you don't want that. i am running to4E on gsr stock block and those are my 8psi settings.

gamble, you basically have the same set-up as i do. we are using injectors twice the size of stock. you need to lean it out like i said on the lo throttle, ALOT. and put 10% more fuel on the high throttle. put the throttle points like i said 20% lo 65% hi. you need to play with the idle. at 1K and 2K rpms on the hi and lo throttle i am at -34%. it idles at like 800 rpms. nice and smooth. this is my setup after numerous searches and talking to people and reading posts. i have found it drives the smoothest with these settings. i am at 8psi using profec b spec 2, 450 cc injectors, walboro 255lph fuel pump, etc. try it, you'll still be rich all the way through the rpm band but it's better than being lean. just try that and if you need to make changes then make em. you may need a little different setting than i do. it should be close though.
