KC Turbos Whistler Stage 1 Drop-In 63mm Turbo 11-19 Ford 6.7L PowerstrokeMany would argue that the 6. 7 Powerstroke is the best Ford diesel ever produced (don't worry 7. 3 enthusiasts, we've got your back!). That said, probably the biggest issue that has plagued these trucks is the factory VGT (Variable Geometry Turbo).

Many would argue that the 6.7 Powerstroke is the best Ford diesel ever produced (don't worry 7.3 enthusiasts, we've got your back!). That said, probably the biggest issue that has plagued these trucks is the factory VGT (Variable Geometry Turbo). The earliest model 6.7's, specifically 2011-2014 model years, had notorious turbo failures especially on trucks running above factory boost levels, so for 2015, Garrett made some advancements that improved the reliability, and then in 2017, also made further improvements. Now, these trucks are incredibly easy to increase the power on, but the stock turbo, no matter the year, can really only take so much before it just can't keep up. And this is where the Stage 1 Whistler from KC Turbos comes in.

The Whistler features a 6.0 Powerstroke style billet 63mm 10 blade compressor wheel that will vastly outflow a stock turbo, but also deliver the unique 2003 turbo whistle. On the other side, the turbo has an upgraded 10 blade, high flow turbine wheel. The combination of these larger wheels surrounded by upgraded housings will give improved boost control, cooler exhaust gas temperatures, and faster spool-up, making it an exceptional choice for the daliy driver and towing rig.

Because this is built off of the same framework as the 2017-2019 model years, it will bolt right up to those trucks. For the 2015-2016 model years, you will need to add a pedestal conversion kit for a complete system. Now, the 2011-2014's will require an installation kit that converts the surrounding components to accept the later model style turbo. But really, this is the best option you have to alleviate the failure prone early style turbos.

Love it
Color: Dark Green, Size: Small
I got the dark green. Love the sweater and it's warm. I do layer the sweater as well. It is as pictured. Size is perfect to me. I like sweaters to be longer and a bit wider in case it is freezing and I need to layer it. This sweater is perfect for layering. It comes closer to my backside, it is a little wide and not snug, and I like that the sleeves come over my wrists

Still soft but looks terrible after 1 wash. Save your money
Color: White, Size: Small, Color: White, Size: Small
Update: sweater looked great when I received. After 1 wash it looks terrible. Looks like it’s been washed too many times, material fuzzy and piled. After wearing it once, it snagged and the knit pulled through. I would NOT recommend. I had such high hopes. Save your money. Very nice sweater, especially for the price! I love the details of the buttons on the sleeves. It is SO soft. It’s not super thick as I can see my skin through it when pressing my hand up against fabric. However, it’s not see through when wearing it. It’ll be perfect in cooler weather and perfect in the winter with a coat but won’t cause me to overheat when in a heated environment. I do feel like it runs big. I could have sized down a size. Although I’m not sure if it’ll shrink after a wash or two.

Disappointed.
Color: Blue, Size: Large, Color: Blue, Size: Large
This sweater is so comfortable and very soft. It fits well in a flattering, oversized way. But after one wash it is pilled everywhere which makes it look old and shabby. It’s at a price point where I feel compelled to return it.

Perfect for casual wear and dressy style
Color: Dark Green, Size: Small
This sweater is soooo soft and the color is so rich. The fit of it is perfect, not too tight and not too baggy, just right and I used the size guide to pick my size. Just for reference, I am 5'3" and 130lbs, 38C bust. It's well made and washes great. I chose to hang dry mine as I typically don't put any of my sweaters in the dryer to dry, just to fluff them. I have this one in two colors, the green and the tan/beige and I would say they are both a true representative of the color shown.

Love the long sleeves!!!
Color: White, Size: Small
Love it! I'm 5' 11" tall and I purchased this according to reviews. Several people commented on the length of the sleeves. I have a hard time finding sleeves long enough if it's not " tall" sized. It was perfect for me. If this washes nice I'm going to consider purchasing more in other colors. I ordered the white and just love the long ribbed cuffs with the line of buttons. Very soft.
