Before the Cheetah my EGTs would creep into the worry zone on sustained grades with a loaded trailer — after the swap they stay comfortable even in the same conditions. The turbo itself feels well-built, shaft play is tight, and boost response is satisfying.

EGTs dropped noticeably pulling my trailer on the interstate and the turbo spools up way earlier in the RPM range than the factory unit ever did. Install was involved but Fleece's instructions are detailed and everything lined up on the first try.

The performance difference is immediately obvious — throttle response under load is sharper and the truck pulls grades without the EGT climb I was used to managing. Only giving it four stars because a couple of the oil line fittings were tight to access and I'd have appreciated a torque spec sheet in the box.

Runs commercial routes towing equipment daily and the Cheetah has kept EGTs in check through every hot summer load I've thrown at it. Boost pressure is consistent and there's no rattling or shaft noise even after a lot of hard miles.
