Losing RPM's at WOT.

Same exact problem on my 08 250 HPDI, need to have your screens cleaned and filters changed, parts alone were close to $200,,, they will blame it on bad gas and your total bill will be between 4-500 good luck and PM me if you have any questions,,,, also I was told that it is a DIY job but I chose to let the dealer do it b/c they cost a lot to rebuild when you burn them lol,,,, see if one of the filters on from that service cost like $100, if not start by changing that one
