We have had a lot of problems with power on our 8010 this year! Turned out to be the lift pump again ( replaced it three times in the last year-dealer said that they have had a lot of problems with new pumps, 80 percent failure in first month!) Changed it again, and have a whole new commbine! Maybe check how much fuel you get at the secondary fuel filter. Crack the bleeder srew-should squirt out across the top deck! Also, check your turbo control rod. Ours was sticking at the pivot point enough so that the turbo would not boost up quick enough. Good luck!
