Diesel Stage 3 Boost Cooler – Duramax, No Tank (SNO-530-BRD-T) - Chevy/GMC LBZ · LLY · LMM · LML · L5P
Tow cooler. Pull harder. Protect your Duramax. Snow Performance’s Stage 3 Diesel kit is built for trucks that see heavy loads and rising EGTs. The smart 2D-mapped controller blends boost and EGT to command precise water-meth delivery—slashing exhaust temps by ~100–300°F, cleaning up combustion, and adding up to 65+ HP so long grades feel effortless. The compact controller mounts cleanly on the column or dash and doubles as a boost gauge and EGT monitor for a tidy, no-drama install.
Why It Works
- Mapped control: injection scales with boost and EGT to keep temps in the safe zone under load.
- Real-world power: up to 65+ HP (setup dependent) with stronger mid-range and towing confidence.
- Cooler & cleaner: typical 100–300°F EGT drop, reduced soot, cleaner components, and potential MPG gains.
- Non-invasive: column/dash mount—no drilling or extra pods—and does not leave a tuning signature.
