and also what injectors are you running? if it's stock, then 12:1 is the one to use. i used to have 36lb injectors and i needed to use 6:1 so you can get an idea. you probably need to get 30-32lb injector territory to use that disk.

Yep, you either need the 12:1 disk, bigger injectors(what i would recommend) or make sure your fuel pump is operating properly. when you have the cash, ditch the regular FMU, and get a SFMU. you wont be disappointed.
