Merlin,
If your running any kind of power upgrade's with more than 60hp over stock with the Auto, You need to Upgrade the Auto transmission too!.
As for the Injection Pump, I agree with KatDiesel, Jnutter and Evan Beck,The Bosch VP44 Injection Does not cost $5000. 00 unless its the Gold Plated Model.
There is a Bosch Shop here in Bakersfield Ca that has them at $1,100 With Exchange. Every Rebuilt VP44 is rebuilt at Bosch, Not at small shops like with alt/starters and such.
I have 70k on my 1998. 5 215hp Cummins/Auto, Stock it dyno'd out at 178hp. When I installed the 275hp injectors I had it dyno'd again at 235hp,Then auto was fine and Holding well when towing with just the 275hp Injectors.
But! When I added the BD Plug-N-Power to the 275's, The auto Torque Convertor would slip while towing or Not in OD.
So I the added the BD Presure Lock,The holding Power was Marginal at best with this device. So then I contacted Bill Kondolay at Diesel Transmission Technology, And Bought His 80psi Valve Body, And that Did the trick!. The Auto and Torque Convertor Now Hold the Power. The transmission/TC Will not Slip now.
I had the Truck on the Dyno a Couple of months ago with the New Valve Body,275's and Plug-N-Power and it dyno'd out at 270-282hp. Traction was a Major Problem on the Rollers. I Had to "airdown" the rear tires to 25lbs with 500lbs of sand in the bed to keep the rear tire from sliping on the rollers.
BTW, Like many other Rammers out there,I had to replace my Lift Pump a while Back. It had gone south too cuasing a Lope-ing idle after a long hard pull with a 7klbs Trailer up a 12% grade at 6,000ft Alt.
I Hope this Helps.
Get ahold of Bill Kondolay at DTT, He will fix you up!
Doug.
