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?

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?
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?
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.
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 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!!
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. 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.
