1000cc Afi injectors?

[burkgonzo]

I am running 1000cc AFI injectors and I am seeing 88 percent duty cycle on 14.5 lbs with my td05 20g. Fuel pressure is 37.5 lbs. Does this mean they are'nt 1000cc? I know most flow 950 when they are sold as 1k. Im puzzled.

Wow..I dont even know what to say. Are there any numbers on the injectors to see if you can cross reference them? From my understanding if your boost est. is way off your ducty cycle will also be off but I'm nort sure if if it would be that off?

Either you got a HUGE boost leak, or you don't have 1000cc injectors. Pull an injector off and tell us what the numbers are on it.

Well my boost is at 1 bar or 14.5 psi on my Tial wg and I am just using that for right now to control boost.

Just because your boost is set at 14.5psi, doesn't mean the turbo is putting out 14.5psi worth of air. That's just what the boost gauge sees. Your maf could be reading 30psi worth of air due to some major boost leaks.
