Pulling behind other trucks

[Rig Wrench]

The 2 2250s with he551 turbos I did do real well. One needs a bit more tweaking. I think it helps tem hold up better. The engine breathes much better up top, less back pressure. These are both running in the 40psi area of boost. No failures at a constant 100k+lbs. Definitely a sweet setup for that engine. Throw in a 5 inch downpipe and clean up the intake manifold and it gets even better
