I have lots of upgrades, CIMA turbo, Kakimoto Full 3'' exhust, Isky turbo cams, z32tt fuel pump, I was going to add Nitrous, dry fog. I bought the kit. But thought I need bigger injectors. Now my car is not drivable, runs poor, black smoke, cuts out about 3,500. Not sure what to do?. add a apexi safc 2, or call Jim Wolf for a ECU. I was running 14.6 a few weeks a go. I have added a posi. Any ideas?

That means a 14.7:1 air to fuel ratio would become about a 9.0 AFR with just swapping the injectors, which is so rich the engine can barely fire.
You will need to reduce the fuel pressure to a point where the car will run better (but too low below ~30PSI and the fuel won't atomize properly) and defeat the purpose of running larger injectors until you can correct for the injector increase using one of the many available methods...

Im not sure what to do, if I pay $500.00 for a J-W ecu, I may want to upgrade The turbo later may need to get ecu upgraded again. If I get a Apexi safc I will need to program it I have a 4 gas at work, But no dyno. Whats the best way to lower fuel pressure, Fuel pressure regulator?
