Ordered from them a few times. It always works and the powder has very little taste and good consistency. Good comms from the company as well.

I have a 2012 Si with 162k miles. I'd love to make it as fast as a stock V8 Mustang/Camaro. Is it too high mileage to do that? What would I get? Also, it IS my only car and I travel to other states for work.
