So since getting the truck up and running, I started turning the power up but realized that each level brought almost NO extra power. Hmmmm....

While at idle, I noticed that the tst rail pressure and the dipricol rail gauge was about spot on (5-6k psi). After driving for about 5 minutes, the tst rail pressure seemed normal (about 10k psi) and the dipricol rail pressure gauge was running maxed out (25k-30k psi). Wide open throttle the truck would kit 40psi of boost and fall dead and the rail pressure gauge would read 10k psi. WTF.

IT USED TO WORK FINE WITH NO PROBLEMS!!!

So today, I remove the dipricol rail pressure gauge and it seems to have found a bit of power. With the settings on DefuelingOn TM3 Timing2 Rail2 #9 I went from 40psi dead power to 60psi with some umpfh. Seems to made a difference! I still have to turn the power up more to tell for sure.

----------------

I'm sure the gauge is not broken... but the only thing that I changed post rebuild is the location of the sensor. It used to be in the back of the top pump, but no its been located in the rail itself.

Anyone else have this problem? The fact that this gauge could have been hindering my trucks performance for the last 2 years is very concerning!!!!

 

 

What order do you have them plugged into together?
