definately gowith the 43lb injectors, they run like stock and drop right in, no point in cuting it close.

i am 99% sure your stock injectors would show 100% duty cycle right now. i just looked at a log and i see 21ms max at times and i am nearly stock, this is at 5000rpm or so and seems to go down slightly with rpm but with your mods i bet you are over 100%right now if you rev it hight at all.

I want to try to run it on the dyno up to 6200-6400 and see what it does. On the dyno it keeps on pulling, but we had to shut it down because of the rev. limiter. Running it on the street it pulls hard to 6k but then i need to shift . What do you have your timing at when you run on the bottle and what plugs are you running? I cant wait to see how it what it does with some tuning and the bottle.

We need to get some sound clips of this thing up here!

Trust me when I say it is nothing short of impressive for a stock headed, non stroker vehicle!!

It pulls like a **** too. The bastard always stops by my work right before I close. He follows me onto the freeway on my way home just so he can test out how well a new part works by how bad he smokes me!

I don't get it. Aren't the HD 6.0L trucks slower stock than the non-HD 5.3Ls? All he has on me is the cam and electric fans and from a roll he pulls away from me like it's nuthin. Then again I am betting he has a good 60+rwhp on me.

Congrats bro! Blk6.0HD Hahahaha

i got the tr6 plugs and am seeing 24deg anytime i floor it, when you use the nitrous wet kit your duty cycle will actualy go down some since you are displacing some of the NA air with nitrous.

i think the 6.0's are very under rated from the factory. they are also pigs

here is a screen shot from efilive, it is the coolest. you can see i am at 21ms on the pulse width, it goes down a little as the rpms go up but this is a stock motor with crap exhaust. just thought it was cool so i am posting it.

Here is the dyno pic. From your air fuel reading, it looks like you are out of injector and going lean above 6000 rpms.

Thanks for posting those for me BigTex and for any info eneryone has given me. Im trying to learn as much as i can about tuning before i go and start messing with the comp.
