Andy | BMW M135i

The vehicle was already running a Tony banks turbo back exhaust system, Burger Motorsport Intake system and Burger Motorsport JB4. Andy supplied the Forge charge pipe and asked us to supply and fit a Wagner cooler and charge pipe to his. With the parts fitted and the JB4 set to map 0 we ran the car up on the dyno. We then ran the car in map 2 and 5 to see what offered the best performance and on this occasion it was Map 1.

JB4 Map 0 296whp | 341lbft

JB4 Map 1 After 353whp | 393lbft
