Nothing will make a twin turbo run bettet
The claim of 160 HP gain is not exaggerated....gained 8 pounds of boost, accelerating is blowing, installed with a twin tube intake made my twin turbo BMW go from fun to drive to almost scary fast...never thought my 4 door AWD would ever come close to my C6 Z06, but the Burger Motorsport JP4 has proved me wrong...and being able to change the tune from your iPhone from mild ( their version of mild is still nuts) to wild is just crazy...an unexpected benefit is at 85 mph on the freeway (posted limit is 80) I got a 5 mpg boost if I set the cruise and kept my foot out of it.... if you can do just one upgrade, this is the one.

a bit hard to install if i'm honest since my oem plugs didn't match perfectly. it broke my car for a week since i blew my spark plugs and coil packs on the first night of use and had to wait for shipping but now it works like a dream. my 335i shifts really fast and makes a ton more boost now and its positives seem to outweigh the negatives. also it blew my blow off valve off my charge pipe on map 1 so be careful
