Had this turbo on my 6.9 for roughly 4 years now. I've posted about it several times. I mod'ed my Banks kit, and intake manifold, but it was worth it. It's not gonna tow like my '17 F450, but I wouldn't expect it to. But, it is much more pleasant to tow the camper than it ever was with the Banks kit.
No I haven't dyno'ed it. Likely never will unless an opportunity to do so falls in my lap. Don't care to be honest and I really don't have the time to hunt for a place to do pulls. All I care about is how much it improved the hauling capability of my IDI.
And, for guys asking for making dyno runs with multiple turbo setups on the same rig..... That's a huge task. Do you know how much work goes into swapping turbo sets out of a rig? How much time and effort that'd take? That's fine if you have nothing else to do and money/time to burn. I know I don't. I know Mel doesn't. My suggestion would be to buy the kits, find a dyno, and enjoy doing the comparison yourself.
