Awesome product and great service.
The guys at BSI probably have the best customer service I've ever recieved. Extremely knowledgeable and won't up sell you on things you don't need. Purchased this turbo and dual wastegates for my 5.3 project about a year ago. The stuff has held up great with absolutely zero issues. What a combination...I ordered this turbo in a non ball-bearing configuration and it's amazing how freely it spins. 10/10 will be a return customer.
