Can't speak to the air filter but the turbo was certainly working. IIRC it was a new turbo as the old one had developed a hole in the turbine housing. A big part of the reason we ran my chopper on that tractor at the time was to try and get more mileage from the big tractor as they had been using a small chopper. They had a 3940 and mine was a 3960. Neither of us were too impressed with the throughput. I'd hoped that I could have doubled the throughput compared to what the Ford was chopping as we were picking up bigger rows... but the pitifull Deere harvester heads can't seem to pick up and faster than 4 mph consistently... so we really just couldn't get any more into the machine. The tractor had the power to handle it and the chopper had the throat to take it... we just couldn't feed enough in. Again... it goes right back to my point about running an engine at rated speed and light loads. They're going to burn the fuel anyway. It's up to you to get the work from the fuel.... and about right sizing the tractor. If we'd gotten the production we were looking for from the chopper when it was on the 4440 then I think fuel use per tonne would have been close to the same.
As far as the sarcastic remark about the plow... yeah, I probably can show you a 7710 or two that has pulled more plow than a lot of 4440's. Another neghbour of mine pulls a Kverneland BB115 at 6x22" with a fully ballasted 7710 MFWD that he's got turned up to somewhere in the region of 120 hp. Does he pull it fast.... No. I think 3L is probably about all it makes most times and only on dry ground... but it did it for a lot of years. The same tractors also hauled an 11' BushHog offset with 26" or 28" blades, buried to the spools. He claims that disc weighs in at 5.5 ton. All I know is that it has roughly 4x6 bar for it's side frame rails... so I know it's heavy. My 9' offset with 3x6x5/16" HSS is roughly 2 ton... MFWD 7710's when heavily ballasted, on 23 degree radial all traction rubber... will pull like hell. He's had scaled loads of 26 tonne behind his when hauling manure... and I believe 22 yd of wet peat, dug straight out of the bog on the same spreader. He broke 7 drawbars in the span of about 1 week before he made his own... which is now the full width and depth of the housing... along with a rear support strap on the top of the housing to hook the two horizontal holes in the axle center housing. These tractors can nearly have their front ends balanced by drawbar loads alone while carrying 600# of suitcase weights and probably another 800# in the loaded front tires. They don't lift but they're on the edge of controllable climbing a hill. That's been the life of my buddy's two 7710's and my one 7710... and probably 25000 hours between the three.

Today's Featured Article - Restoration Story: Fordson Major - by Anthony West. George bought his Fordson Major from a an implement sale about 18 years ago for £200.00 (UK).
