This plug and play tuner attaches to sensors in the engine bay and works with your factory DME tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag. Power gains on an otherwise stock car are up to 25hp and 40tq to the wheels. Installation is very discrete and it quickly removes without a trace when needed. Fuel economy during normal driving is unchanged.

Features:

• 25 HP gain
• 40 LB-FT gain
• Plug and Play

Fitment:

• BMW F10, F11, 550i 2011-2013

NOTE: Prior to ordering review the install guide and take a photo of your MAP sensor. Email it in so we can tell you whether you need the TypeA harness or TypeB harness
