Do 24v 5.9's need to warm up?
 

For about ten minutes after I start up, here in balmy SoCal, there does not seem to be much power/throttle response. After about ten minutes it is fine. Is that normal? If it is, what is it that causes it to do that? Thanks

I know mine runs nice when she gets warm but is a littlle doggy when cold but thats just diesles my wifes 6.4 powerchoke is the same way

I have been told that the 24 Valve Cummins was designed to run at 190* for best performance

Your rig is fine bro. Mine does the same thing..... and hauls balls when it warms up.

Thats normal. Any engine runs better once warmed up. Most diesel programmers will not add power until atleast 140-150 degrees. Some you are able to turn it off. Its safer to get heat in the motor before beating on it. :c:
