Gaidenmade is one of the premier mechanics in Las Vegas for BMW and Audi. His company shines in aftermarket performance. My stock 335xi was turned into a beast because of him. He put serious time and effort into my car and designed a custom tuning package. My installs performed by the mechanical genius: Burger tuning jb4(stage 2) Injen cold air intake Active autowerks charge pipe Evolution racewerks downpipe catted Custom(and I mean from aluminum, rolled and welded and fit) high flow quad exhaust powder coated KWV1 coilovers Wheel spacers Short throw shifter Custom welded grind cage to deal with uneven surfaces and speed bumps And last but surely not least: methanol injection kit with boost gauge mounted on dash. Premier, professional, flawless work. He did all ECU tuning and computer work too. The guy is the real deal for the most simple or advanced projects. As a surgeon with limited time, and expect precise results I couldn’t recommend a better person.
