Building the line of Stealth Turbos meant designing a turbo that's safe to tow with, fun to drive every day and a class leading competitor. If you think street-able, clean, stealthy power is cool, then this is the turbo for you.
Duramax Tuner's custom-built Mach 2 (67mm) compressor wheel is specifically designed to maximize peak power while maintaining a wide, useable powerband. To fit the monster compressor wheel, they developed a unique, OEM appearing, anti-surge ring, which nestles in the factory compressor cover. Matching the class-leading compressor performance meant updating the center section which is fitted with a 360-degree thrust bearing to increase reliability under heavy load transitions. The wastegate was even updated to make sure you have the most amount of power and the quickest spool-up.With the compressor side and center section put together, a turbine wheel and exhaust housing upgrades had to be made. The LB7 Stealth Mach 2 (67) features the largest turbine available in an IHI-style (stock LB7 turbo) frame. This dramatically reduces drive pressure and allows for serious power production even at high RPM where the IHI typically falters. This monster turbine helps you achieve as close to a 1:1 ratio between drive and boost pressure, which not only helps make more power but also manages EGT's (Exhaust Gas Temperature) under heavy load.

Cat Approved 🐈
It's a little thin but still has some fluff; a true fit for an all-season comforter which i like. Its also very true to its size (I needed a full size and it almost seemed a little small when i put it on, like i should have ordered a queen size but whatever it works) It's 100% polyester so it's smooth and soft and hopefully will last for a long time (im against overcomsuming so clothes and sheets i buy i want to be able to last for a decade or more).
I loved the pillow shams it came with and like how they zip. Decent value for your money--you're ONLY getting the comforter and pillow shams so its a fair price and it's washable.
Only thing is they had a few stray threads but nothing in the seams was coming off which is good.
The reverse side is also definitely a more pinkish purple and not lavender purple as advertised but that's fine; it may also just be a lighting or contrasted against such a deep purple color that makes it look more pink. Looking forward to sleeping in it!
