Very overdue review! These cats have been of great help since my dyno session with them last year! Bob is a well of knowledge, and can clearly and concisely tell me what the deal is with x y and z. He is kinda hard to get in contact with directly, but I understand the industry is demanding and these cats have a bunch of work to complete in a day. Randall has been a great help with setting me up for success! Very patient with me when I was asking a ridiculous amount of questions due to my uncertainty and made everything crystal. He is a very personable guy! Have had my dyno tune done by them, recently purchased an update to my tune, and 10/10 will be happily driving 5 hours back to them in the coming months to get SC'd! Seriously, a phenomenal bimmer performance shop. Facility was clean, their waiting area was cool / comfy the day of my dyno session! (It was hot as (expletive) that day!) Don't hesitate to hit these dudes up! For performance or maintenance. Their presence and praise in the forums speak VOLUMES!
