With the correct modifications, the factory Garrett VVT turbo found on your Duramax can be built to support 650 horsepower. This Stealth Series turbo upgrade is just that, which means its a direct bolt-in replacement of your stock turbo, but you'll gain big power and drop massive EGT's (Exhaust Gas Temperature).

Building on the popularity of the Stealth 64 in the LB7, the Stealth 64 VVT project has taken a stock appearing LBZ/LLY/LMM turbocharger and overhauled it to meet the demands of the Duramaxtuner team.

The stock LBZ/LLY/LMM turbocharger runs out of air at about 530rwhp. It has trouble controlling EGT's (Exhaust Gas Temperatures) on extended pulls past 400 horsepower. The Stealth 64 VVT extends the engine's useful power curve by another 120 horsepower, to 650 rear-wheel horsepower. Furthermore, the Stealth 64 VVT is much better at controlling exhaust gas temperatures under sustained load when towing up long grades at high power. This is accomplished through the use of a specially designed billet compressor wheel which is matched to a higher flowing turbine assembly. This match offers the best balance between quick spool-up for driveability and overall compressor flow for peak power, ideal for truck owners looking to make 650 RWHP.

The Stealth 64 VVT is an easy-to-install upgrade that spools up quickly, controls EGTs under heavy load, allows for turbine braking during towing scenarios, and kicks the competition to the curb when leaned on.

The Stealth 64 VVT Turbocharger comes completely assembled and balanced with the following:

Super comfy and pretty
Color: Black, Size: X-Large
Fit is nice and comfortable!!! Soft in the inside as well! It’s not huge but also doesn’t stick to me. You can literally wear it down (casual with jeans or shorts) or dress up (like I did for Mother’s Day with a nice skirt and jacket) Seems breathable enough for our California heat

Great buy. Love this shirt!
Color: Teal, Size: Medium
This shirt is so great. The color is absolutely stunning and vibrant! The material is so soft and comfortable. I use it as a casual work shirt with capri leggings, and stay comfortable all day. It definitely runs a bit large. I am short so it hangs very long but I like my shirts that way for work. I am usually somewhere between a small and a medium and I like a loose fit so I got a Medium. This was almost too big for me to wear, but I am making it work. I plan to buy this shirt in multiple colors and will get a small next time. For reference, I am 5"2', 126lbs, bra size 34 C.

Feels soft!
Color: Black, Size: 4X-Large
The fabric is great, as is the weight, fit, color. It covers the backside and doesn’t bulge around the hip. Would love to see it in several colors!

Really great quality and fit for the price
Color: Navy Blue, Size: Large
These tank tops are beautifully cut, the colors are great, the fabric is stretchy and comfortable and they don’t look at all cheap. A very welcome surprise that they exceeded expectations. I spend the entire summer in slim fit tanks and A-line skirts with a jean jacket or shirt over and ended up buying practically every color because I like them so much - can pair them with much more high end items and they don’t look out of place.
