Vehicle-specific testers for Chevy: Duramax 6.6L.
Check the engine and year in the product name, or text us a photo of your setup and we'll point you to the right kit.
Most Chevy testers here are for the Duramax 6.6L diesel. The Basic Kit, Pro-Kit and Shop Pro-Kit fit LB7, LLY, LBZ, LMM and LML engines, and the 2017 and newer L5P has its own premium 30 PSI tester. The Basic Kit is a 30 PSI kit you fill through a Schrader valve. The Pro-Kit is a 60 PSI kit with a 5 ft extension line and shut-off, and the Shop Pro-Kit adds a regulator to the extension line so you can set the pressure exactly. There is also a tester for the 2010 and newer Cruze 1.4L Ecotec with the stock turbo, plus the charge air cooler kit for Class 7 and 8 trucks. Every kit is billet aluminum. Start low and work up toward your normal boost while you check the intercooler boots and clamps. A boost leak is one of the most common reasons for a P0299 code on these trucks.
