Kc turbos are awesome and customer service is great too. There is a lot of people on this forum and others like powerstroke.org and powestroke army that will agree.

I wouldn't run anything from sinister, even if it was given to me. Customer service is awful and they won't stand behind a warranty.

 

KC Turbos hands down. He will stand behind his work and make sure you have one of the best (if not THE best) turbos available. He can also answer any questions you have before you buy anything.

 

Make it a 3rd for Charlie at KC. I run his 1.5 and love it. Customer service is top notch...you have a question, he will answer it fully and in "truck own terms", not "big business" terms. LOL.

You can't go wrong with KC. Sinister is a joke, and I've heard too many people complain about high EGT issues with a Powermax.

 

I just bought a billet wheel from KC, the main reason I choose him was because of his customer service. It took me about a month to finally choose, but I'm very happy with my choice. Charlie has always answered my email the same day!

I bought a rebuild kit and billet wheel for my stock turbo. it fits like a glove and looks amazing.

 

I love my KC stage 2!
