Compound setups on the L5P have always meant a one-off custom build. We saw a platform that didn't have a ready-to-order option, so we built one that bolts in right.
A big single turbo on the L5P is a blast, but it asks you to pick your moment: peak power up top in trade for lazy spool, climbing EGTs under load, and a narrower band to work with. This kit keeps everything that's good about the truck and stacks more on top. Instead of deleting your factory VGT, we put it to work as the high-pressure unit, keeping the quick low-RPM response and precise boost control GM built into it. A properly sized atmospheric S400-frame turbo then picks up the airflow as power climbs.
With two turbos splitting the total pressure ratio across both compressor stages, you get a wide powerband that comes on early and pulls everywhere, with lower EGTs when you're loaded up or leaning on it. It tows like it's empty and still lights the tires in third at a roll. Easy to live with, and every single pull leaves you laughing and going back for more.

Design & Manufacturing
Design & Manufacturing
This kit was built to fit and function like it left the factory that way. We started with a full 3D scan of the L5P engine bay and the manufacturer's CAD data, then designed the whole system in CAD, refining it over five iterations and multiple prototypes to dial in turbo placement, exhaust routing, and serviceability.
The tight packaging on the L5P was the real challenge. We engineered the hot-side piping to retain factory downpipe routing, stay compatible with aftermarket exhaust, and keep exhaust components out of the wheel well. Hot-side is TIG-welded stainless with CNC-cut flanges, compound-bent where possible to cut welds and add durability.
None of it was signed off on a screen. Everything was validated on our own shop truck, where it lights the tires in third at a roll and never gets old.
