so welp i went to stick my truck on the dyno today and got the ve table really good and went to make a pull and injector duty cycle got up to 153.8% duty cycle..these are stock injectors..so tell me what size i need to i can waste more money on this basterd

 

8.1L marine injectors - 43 lbs/hr

 

something is wrong n ur tune put back the mass air meter and check it again the most i seen with my truck was like 115% dc

 

Im with devil something is off.

Where you spraying, when you got this high DC?
what is your wot fuel pressure?
what was the afr?

 

I have a set of new 8.1L truck injectors (31 lbs) that I never ended up using that I will let go of for $150 shipped to your door if your interested in a below $330 solution to your problem.

 

afr was 12.5 were it is suposed to be untill 5200 it leans out to 14.9....ive tryed to add more fuel from that point on up and it dont help...im tired of screwin with this thing..gonna take a break from it for a while..then start checkin everything over again

 

sounds like low fuel pressure, clogged filter, etc... i would check the fuel pressure at WOT where it leans out. it should be around 58psi if i'm not mistaken.
