After months of testing and data logging, WDi is happy to introduce our DIY (Do It Yourself) 6.7L Powerstroke 55% over injection pump barrel and plunger kit.  You will have to remove your injection pump in order to change the barrels and plungers. We have tested these on the 6.7L Powerstroke injection pumps, with a 2.6 pulse width tune and this pump never dropped any rail pressure. Please note: this set up can also be ran on stock tuning. 

**This kit includes the barrels, plungers, bolts, hats, and o-rings. There is a $200 core charge, you must return your old complete barrels, plungers, and hats.**
