helper pump on 6.7
wondering if anyone has installed one yet. i put one on my 2006 and it was the difference between nite and day! I figured these 6.7 trucks need one too. i think a helper pump would pick power up even on a stock truck. i know that line pressure goes to zero on a stock 2006 under load.
