CM871 Turbo on CM2250

[Aleeex]

I remember seeing a thread on this subject but I cannot find it now.

I am looking to install the CM871 turbo on my CM2250. My turbo started pushing a little bit of oil and I am not a gambling man.

Who can retune the truck for that turbo? I believe I tried sending a message to a member before and never received a response.

Truck is demandated. Maybe that someone can take a look at the tune itself. There is a hill in TN that my truck likes to boost to 39-40 psi.

39psi boost on a 2250 will kill it.

36 is max it can handle.

currently sitting in the truck trying to figure out how to pull the file

Also, I am going off the OEM gauge in the truck. I should probably verify this with an analog gauge

is it deleted and if so by who? if the tuning isnt from someone here it probably is hitting 39psi and killing itself

Rawze knows him, but supposedly he is getting sloppy.

Maybe if I buy Rawze enough beer he will teach me a couple things so I can test them out on my truck.,



Tuning related that is

Aleeex, why would you do this? The 871 turbo, as Rawze already told you is unusable on a 2250. Why put on a bigger turbo if the motor can’t handle the extra boost it will generate. As I understand it the stock has no problem with supplying enough boost in any condition.

Talk to Magard, he did this very thing. And I think he said it was a waste of time. (Magard please correct me if I am wrong)

Just my .02. I pull up to 105K gross just fine with my 2250, stock turbo, and properly demandated.

Rawze did not say that.


And I am not after more boost.



I want to test a theory that I have, and this has been done. No one really talks about it.


I just checked my messages and I sent a message to Unilevers over a year ago. Maybe he will see this thread?

an He561 flows a lot more air than a he400

Its possible that I wont even need to run as much boost to make the same power. Less boost = less intake temps
