BMW 335i...Vishnu retune

My car only has 300hp from the factory and its boosted but that does not mean it does not have serious potential. The new BMW I6-TT is going to be a sick ass ride. I am really interested in them, if I can swing it, thats a car I would buy. Im looking to get rid of my Denali because its just a gas killer. I would love to single turbo a new 335i. Its going to destroy the e46m3’s
