You need fuel control. If not you will run Obscenely rich. But if you do that and a Fuel pump, you will be able to squeez every last bit out of your 14B and not get fuel cut.

there were 510CC injectos that would work right with your car, they came with the 16G equipped motors.

thought you had an afc2.... or do you have it mounted, but not hooked up like your front mount intercooler a few months ago ?
