So far I have I'm impressed. I had a little trouble with installation. It was supposed to drop right in but didn't mount up to my exhaust. For some reason my truck is an 06 but has 04 exhaust on it. The turbo was about 2 inches shy of reaching the exhaust. Went to an exhaust shop and got it mounted up by just loosening the pipes at one of the slip joints and extended it to mount up flush to the turbo. So far I have pulled an 800 mile round trip gross weight of 27,140lbs up to the High Sierra Nevada Mointains hauling two Jeeps on a 40ft goosneck. I was very impressed with how the turbo spooled up and pulled. I also added a tuner from 5.9 diesel at the same time and used the tow tune. She did want to run hot so I had to watch my speed and what gear I was in. Overall happy with the purchase.
A little over a year ago I was upgrading my injectors and warped exhaust manifold and wanted to do a turbo at the same time. The BD tech support was excellent in helping me choose a kit that works for me at my elevation. I couldn't be happier with the setup! It's a hair laggy on the bottom, but you learn how to drive it to minimize smoke.
Easy install and great customer service helping choose the right product. Thank you again!
Was exactly as it should have been and installed without any issues.
