anybody?
I have logged the truck with EFI
and was looking at some files, and looking for info as to why my motor feels like it sits..

what are you loging with. many scan tools have "injector duty cycle" and that just puts it into a percentage for you. 100% is maxed out.

the other thing you can log is pulse width. at 6000rpm you have 20ms to fire the injector. if you log pulse width and see over 20ms at 6000rpm then they are maxed.

anything over 4500 and it is sitting at 101%

I figured you would be close .. what do your o2's look like at up that high?

if your a/f ratio is still good then you are ok for now. i personaly dont think it is a problem to goto 100+% as long as you are not going lean.

if you plan on pushing it any harder then you will need some biger injectors and a reprogram for them. the 43lb units are ideal. they plug right in and only need a reflash to run them.

B1S1 = .968V

B2S2 = .968V

and this is at 107% INJDC1
and 106% INJDC2

that would be high boosted. NA that is really high(rich). if your feeling slugish up top it is probably from being too rich.

man danial i am running a 150 shot and my mods and im not maxing mine out. sure you are not just rich. 968 is a lot for a n/a motor. i am seeing 920 max wiht mine on the juice.
