Moose Pump Review / MPGs
This is going to be a long thread because I want to upload updates and MPG figures as they come in.
The first trip I took with the pump gave me 12 MPG.
This was in moderate to heavy rain, and I was hauling a$$ pretty much the whole way with the trailer behind me. Average speed was between 80 and 85, uh yeah not a good idea but the tuck performed. I think 12 was actually pretty decent considering....
Second trip returned 15.08 MPG with average speed held at 70 and still had the trailer behind me. This is my benchmark for what I expect my truck to return on this particular route at that speed. Generally, it will get 15-16 MPG towing on a good day and today was decent. Sunny, dry, and no wind at all. Traffic was not perfect, but not too bad either. Keep in mind, the 15-16 benchmark is what I would get on summer fuel.
My truck did smell blood with an older GMC on a few consecutive hills, so that likely did something to my MPGs. Caught him on a 6~7% hill. He was doing 70 and slowing down, I was holding 80 in 3rd with the TC locked. I need to train my truck some more not to do that.
Power is hard to say at this point because the transmission desperately needs to be reprogrammed for the larger fuel flow. Upshifting is too early and kickdown too late. However most of my cruising is done in overdrive now even with the trailer attached. 3% hills or less and no downshifting is needed. EGTs ran between 600 and 700 unless being aggressive on a hill. Climbing a 5% grade in 3rd resulted in about 650 EGT and completely smoke free operation (4 PSI boost). Smooth and steady all the way up.
Peak turbo boost is unchanged but that is no fault of the new pump. Either my turbo has a problem, or the gauge isn't reading properly. Given the added smoke at WOT, I'm leaning toward a defect in the turbo itself keeping me at the 12 PSI range. I can't think of anything that I can do about it right now so I will run it as is.
Next week will be another identical trip and another MPG update. If I can average 3 consecutive tanks in the ~15 MPG range we can call it confirmed that the moose delivers in terms of fuel economy at light throttle. I remember reading similar MPG claims posted here before and it would be nice if I can add my data to agree with the rest.
