"The Juice Box v1.1 BMW Tuner is a boost controller by Burger Motorsports for the 2007+ BMW 335i Twin Turbo. It safely increases boost from the factory 8psi setting to 10psi, resulting in an additional 20-30rwhp and 30-40rwtq on 91 octane.
Built using high quality components and OEM connectors, the Juice Box conveniently mounts in the DME/ECU compartment making it 100% hidden once installed. Installation takes approximately 20 minutes and is 100% reversible.
Benefits:
1) Safe boost level for long engine life and trouble free operation.
2) Retains the factory smooth performance and refinement of the 335i.
3) Completely hidden from sight, no struggling with removal before taking the car in for an oil change or service.
4) 100% pass through operation allowing factory altitude correction, temperature protection, fuel enrichment, and traction control to work properly.
5) Reasonable price. Just because you bought a $40,000+ car doesn't mean you should have to pay an arm and a leg to improve its performance."
