Yep,

However my friend put his on first and we both have 6.7's with six speeds, He didn't even make it home before he smoked his clutch. He said he couldn't tell if he was spinning the wheels or the clutch, it was obviously both and the truck barely made it back home.

I wait till about 1900 RPM's before I even lightly step on it and I am careful as I can tell it starts to slip even under low throttle.

I will be ordering a clutch soon! It does have massive power on the high setting!!

I have ran it with my clutch I will say this if your fuel system isnt upgraded there isnt much use in it. The fuel demands are extremely high I say you need a minimum of upgraded (stage 2 or more) cp3 ,but duals are recommended

what does the stage two upgrade in-tale? or what would you recommend adding on my 6.7

I have a S&B with ram, H&S mini max, egr delete and 5 inch exhaust, yep I know that I need the clutch also and I am waiting for a quote. Also when you all are doing the clutches, are you changing out the hydraulics?

Thanks

Hmmm I need to update my sig stage 2 is a 45% over stock I would say that is bare minimum for a good rail pressure if I was going to run 225 regular I would go stage 3 or 4 or dual CP3 the arson isn't on my truck anymore but the rail would drain fast on 225 tune.

And yes the hydros need to be upgraded imo

We did put in a H&S rail plug, but help me out here, is a stage 2 or 3 including new injectors ?

Has anyone dyno'd a high setting H&S without injectors vs with, set up similar to what I have. H&S advised me that barring the clutch it should be fine.

I would go stage 3 if your going to add injectors I think I personally am going to go with a 120% pump when I change injectors because injectors would tend to drain the rail even worse. there should be a guy here named kmk he would know a good bit about it I think he dynoed with the 225 tune with stock fuel system

hope this helps
