Who can tune this thing right?!

They don't spool slow without over fuelling to achieve it , they actually spool just as quick if not quicker than the vgt and you don't close the shi#t out of it creating a heap of back pressure to do it . As far as running down the road, if you were to log it , they behave nearly identical to a vgt . Again I have done it , each to there own . The Borg warner crap fitted without a waste gate is a mistake but a hx60w as used by cummins is a very viable option for those that want something other than a vgt.

I still say -- Ain't no damn way in hell it is more efficient than my VG. -- or for that matter -- 100% as effective. When you get hyper fuel mileage, even the slightest things of all make it drop by a LOT. it is nowhere near the same as going form 6.2 to 6.1 mpg,.. When something effects fuel mileage that is very high on these trucks, that same something can drop it off by as much as .5 mpg and cost someone like me another 2,000 gallons of fuel in a year.

I never said that the HX60 does not get somewhat close,.. but I still say it is not quite as good. not only that, but it has a bigger air-flow than my turbo and the bigger the turbo the less efficient they become to fuel savings on mid-tier engines like mine (and the bulk of other trucks in America).

Someone is more than welcome to mail/send me an HX60W if they want to know exactly how it stacks up, instructions on how they want it set, manifold if needed, and a program that you they have perfected for the mid-tier CM871 with it. I will put it all on/in my truck for a month or 2 and see how much my fuel mileage changes. If my fuel mileage changes by even one tenth, I will see it clear as day on the fuel mileage tracking software I have that tracks fuel mileage based on state to state and fuel stop to fuel stop with more than a million miles of known values in it and not some stupid average.

My wife and son drive the truck, so it would be a fair test. That tracking software is so sensitive to changing fuel mileages that when I put on new tires last time, the whole graph dropped across the board for the first 80,000 miles until the new tires got broken in.





It had better not haze or make any kind of black smoke under snap acceleration test either,.. not even a little bit, because the truck goes to California almost every single week, and NJ once in a while and has been emissions tested a few times in the past randomly. -- IT MUST PASS A SNAP-ACCELERATION AND EMISSIONS TEST like my Vg already does. Otherwise, they are going to be paying the fine for me too!.
