It seems like I recall either reading or hearing that the lines would need to be upgraded as well...maybe the lines are a little smaller than the 08-10?
SPE vs Confederate Diesel side by side review
CFD price 3199
SPE price 3000
CFD turbo options s363, s366 or efr which can all be purchased from any diesel supply house and we can provide replacement part number
SPE turbo options s363, s366 with SPE cut housings, these turbo's will have to be replaced by SPE if required
CFD exhaust includes headers and uppipes with 40% increased flow
SPE Uses new uppipes with the same restrictive factory manifolds
CFD kit has a new aluminum intake that replaces the factory intake
But the factory intake can still be used if the customer really wants too.
SPE just reuses the PLASTIC factory intake.
CFD has a custom pedestal and oil line kit.
SPE has a custom pedestal and oil line kit.
CFD kit has a custom 1/4 oil feed straight from the factory oil galley
SPE uses stock oil port off cam bearing which has been proven to be insufficient for an oil cooled turbo.
CFD has a lifetime piping warranty, 12 month turbo warranty, and 30 day money back guarantee.
SPE has a 90 day limited warranty.
CFD kit is in stock
SPE kit is 3 weeks away
Both kits can be installed with the factory emission system in place.
This comparison shows the added value you will get when buying a Confederate Diesel Turbo Upgrade.

With whichever tune you are running hot h and s war hammer etc.It seems like I recall either reading or hearing that the lines would need to be upgraded as well...maybe the lines are a little smaller than the 08-10?
We have been told by customers that are on a max effort tune (max effort means maximum fuel stock system can deliver) just bolting our kit on had the following results:
Lower egt's by 100-200 degrees
1-2 mpg economy improvement
40 more rear wheel hp proven by DMAn115 last weekend at a dyno event. ( he mad 38 more rwhp than a stock turbo Spartan war hammer tuned truck)
These improvements are Attributed to our free flowing exhaust which moves 40% more air than stock. The flow improvements come in the HEADERS which only we offer, uppipes and turbine housing.
The fuel lines look smaller outside but they are a different design than the older style dmax and k16 lines. The new cp4 lines are also fine thread fittings where the old style were coarse. The new lines are the same type found on lml, 6.7, and vw cp4 as well as allot of direct injection gasoline applications. These lines will be sufficient for fuel delivery.
We recommend using a cp3 in conjuction with the cp4. We work on over the road applications and have found damaged injectors due to mis timed cp4's which create terrible rail pressure spikes. It is not recommended to install a cp4 when it can not be timed to the engine.
What turbo is dman running from you guys if he doesn't mind sharing? Standard? Billet or EFR? 63 or 66?
Im debating weather or not to try industrials modded CP4 and see how much it can wake up my 6.7. Just a little worried about my rods...
I think you should. 
We'd all be interested to know the power you get out of her.
We'd all be interested to know the power you get out of her.Dman- what hp did you dyno at?
CFD- What hp difference could be expected if Dman went with a 63 instead? Any torque difference? What is the difference in lag at 7000 feet elevation? Which one would be better for towing very heavy loads? Thanks for your participation in this thread and answering all my questions. Could you please tell us a little history behind your company, like how long you've been in this business and what your experience is? Feel free to send me a pm if you would rather do that.

This was our introduction where I had answered this question before. If you have other questions after reading please feel free to postDman- what hp did you dyno at?

You will make the same hp as dman basically but the turbo you will have will be maxed out fairly quickly. We modded his regulator and added a lift pump. I think those were a marginal increase, and I think he agrees.
I would expect you to dyno 40 more rwhp than what you did with a hot tune now on the same dyno.
Talked to a customer today that has one of our kits that he is installing along with the II 55% over cp4...Guess he'll be the one that can tell us if theres a difference!!
That's only due to poor quality tuning with duel fuelers. If you are going to run duel fuelers I HIGHLY recommend getting in touch with H&S personally and having them take care of your tuning needs. They have proven that these bottom ends can easily withstand well over 800 HP on stock rods and internals.For anybody wanting to dual fuel a stock bottom end, we have some updates.
My guys were smart enough to catch this before we ruined the block.

The dyno will not break anything Brian. You need to stop misleading people, even with h and s tuning the stock bottom is not going to hold 800 rwhp longer than a day. I would imaging the engine in that truck has rods or bearing trouble.
Tuning is not at all the issue here.
You are going to risk your good reputation here making ridiculous statements like that?

I strongly disagree. The dyno can very well break parts. If you don't believe me then can up H&S and ask them about their LML Duramax.
The lml that made 1100 on stock rods. When guys go out and try this and destroy there trucks they will be highly upset.
The customer Evan is referring to is me. I will say I haven't installed the 66 yet but that is because I had got some bad diesel and currently having the entire fuel system changed out. As the quality of the cfd kit goes it is very nice and the welds are good. Also customer service at cfd is some of the best I've had. Any issues or questions I've had they've been able to answer. I'm hoping the II cp4 will help with my fueling issues till I can get a dual fueler.Talked to a customer today that has one of our kits that he is installing along with the II 55% over cp4...Guess he'll be the one that can tell us if theres a difference!!
It made 1016. Obviously I'm not saying that these trucks will run reliably at that power level (800+) for any length of time. My point was that they were trying to purposely window the block in that motor and made multiple passes that were well over 600 RWHP and couldn't get the rods to fail. Tuning is the key to making higher hp in these engines without destroying them in the process.
Look at the lbz or lly duramax's. Everyone said that you couldn't break 550 without throwing a rod. Then tuning got better and now guys are making 650+ on stock internals on the motors and everyone said that couldn't be done. They are able to do so with advances in tuning technology.

Brian they stated timing on both tunes, they never went over 15 degrees on the 6.7, and they went 40 degrees on the lml. When you have negative torque that is bad tuning and yes bad tuning broke the lml not power.It made 1016.

So how long do you think the truck with this rod in it ran with the current tuning?
They were running (still running I believe) the chit out of that 6.7 at 615rwhp all day long with 40" tires and that was on fuel only. They couldn't do much more for fuel as they were only running a 66mm single non-vgt. Had they had compounds like on the LML then it would be a lot higher number on fuel only as they were quickly running out of air for all the excess fuel. I know they advanced the timing on the LML but it wasn't to 40° they were going to but didn't. They were running somewhere in the neighborhood of 34° iirc.
Again I'm not saying that the stock bottom end in the 6.7 will hold up to 700+ of everyday abuse. I simply said that people need to throw this magical 500 reliable max hp before throwig a rod number out the window. Yes these motors were throwing rods at 500 hp in the beginning but that was also when tuning knowledge and capability was in the early stages. As time went on and still goes on there will be greater advancements and have been that will allow more power on stock bottom ends in these trucks.
One more thing on timing. You can't compare the two engines and the timing. That is apples to oranges. Everyone knows that 25°+ of timing in a Duramax isn't chit. You have to know the limits of the engine and stay within them.

The Ford has a longer stroke Brian.
So how will that affect timing?
