Help!! With "fuel cut"

Stupra · 09-02-2008, 06:06 AM

Hey there. If anyone could give me some advice that'd be great. I've had my car for 5 years now and just recently did the 550cc injector and lexus afm upgrade. Here is the symptoms I'm having: Car runs a bit too rich. It smokes black real bad at the initial crack of the throttle then clears out. I feel like I've actually lost power since the upgrade and I keep experiencing "fuel cut" here and there when I down shift. It's only when i put a big sudden load on the engine. It doesn't happen through smooth acceleration. Can anyone give me advice on tuning the air fuel? Or maybe where to time it? I haven't touched the timing and I'm wondering if I need to. I've given the computer PLENTY of time to adjust also.. Thank you!
