I’ve got codes 0253, 1689, and 1688 so I think I did a pretty good job of cooking the vp44. DAP is getting me set up with a new one but before I put it in, does anyone have any recommendations for things I should look at to preserve the next pump?

 

i have over boost code 0234 so I’ll check the waste gate to see if it moves (I guess?)

 

also am planning to check ac noise and do the w-t mod. 

i have the DAP intake elbow, quadzilla, and stealth plate coming too

Yes you need to do a W-T ground wire mod.

 

This is suggested even by Auto Computer Specialists for ECM protection.

Means the boost went too high because of no boost fooler.

I would skip the intake elbow because there is only a 10 HP gain over 600 HP of engine power. There is nothing to gain really for a daily driver because we never just hold the throttle wide open for miles.

 

Second thing is warm air in the manifold is desired really after all my study work. I'm running a 200℉ thermostat from a 6.7L Cummins and pushing intake temperatures in the 80℉ to 140℉ realm for efficiency reasons. My EGT's are super low and Engine oil temperatures are always 30℉ to 35℉ below coolant temperatures. Cold air intake steal efficiency from the engine because cold air CANNOT ignite fuel in proper timing. 

 Also once she is up and running again add 2cycle oil to your fuel. It will help lubricate the vp44 pump. Very important. 

 

Thank you for the replies. Looks like the braket holding the vp on from the bottom is broken. I’m going to try unbolting the power steering there and  see if I can get that whole bracket off to take in to the welder. Removal was easy so far
