    We have a Granite gu713 in the shop now, it has had a history of low power for a year or more. turbo seems to be ok. regen light was on the dash last week, the driver took out the filter and blew it out with a compressor, light went out on the dash but the low power problem persists. the only active fault in the diagnostics is for the turbo. Any ideas? the truck has very low mileage as it is a drilling rig.

    Just blew it out with a compressor? Normally I've seen them cleaned out in a DPF oven. Bakes the filter at high temp while bursting air through, most shops and maintenance facilities have them. Be worth the money to pay for a couple dyno pulls under diagnostic if the problem has been persistent for over a year.
