The screen is in the canister, down about an inch on the drivers side. Turbo should be ok with no play. What's tied open is the ebpv, no big deal. The connection for it is under the turbo, two wire connector on the drivers side. I'll at least bump you up for more help on the power loss. I'm not sure

the 94's can be chipped FWIW. That was just an idea worth checking. If it hasn't been chipped, Can you get the truck scanned?

You're probably just maxed out rpm's while cruising. I thought those came with like 4.56 or 5.13 gears, that's why you have such great low end and no top. I'd say you need to gear up if you want to cruise on highway better. Have you owned the truck a long time and it's gotten worse or did you just get it?

Mine with 3.55's is at 2050 at 75. 4.10's would be about 5-600 more. I'd say 4.10's would be fine with that big truck.

I am rarely on the highway and when I am it is usually not for long.I pull a landscape trailer 90% of the time.Also pulls a small backhoe or skidsteer.So I like the low gears for pulling.
