Lift Pump??

It should keep positive pressure and supply to the CP4 for you, otherwise you starve the system of fuel on the big tune. 1) You can hurt the CP4, 2) do you really want the P0087 and P1093 problems?
Dont want those. Havent had them yet. Just wonder if I should have head studs put on first or lift pump..
Well I am worried about the max effort 200 hp on #5. For right now. I know i snapped a head bolt with a 75 hp tune from the neens outta so cal towing my 10k fifh wheel in Glamis. Now I regularly tow the 16k toy hauler and dont want to blow head gaskets.
Not exactly the same engine.. if you’re worried about it run a actual tow tune. More around 30-40 hp.
What I mean is I know its not the same engine. Tho it’s different the trans coudnt handle the power. I want to make sure the engine is set up for the power
Didnt say it was. I was saying that with a small tune snapped a head bolt. On an old engine. Im sure it wouldnt have done it stock. Chris is a great tuner which is why he only wanted to put a small tune on it as well as the miles on the trans. Ill get a lift pump tho, thanks!
How are you so sure it wouldn't do it on stock? LLYs are known for their overheating tendencies and blowing head gaskets too
Snapping a head bolt is rare on any year Duramax tuned or stock. What makes you so sure it was tuning related?
