Duramax is king of the mountain again

If true about the HPFP, that's potentially an outstanding change by GM. That CP4 issue really loomed large when I was looking at the various diesels last year. If they also fixed the DEF tank, the only remaining thing I don't really like on the GM is the IFS and truthfully that's probably not a very big deal - I just kinda like having solid tubes on both ends of the truck.
