G-POWER E90 / E91

At G-Power, the most popular BMW model range receives the treatment necessary to step out of the mainstream. Whether petrol or diesel powered, sedan or estate, G-Power offers components for each model in order to let a car arise that suits the customer’s individual demands.

Starting with the G-Power BI-Tronic and D-Tronic performance software setups and in-house designed SILVERSTONE wheels through to coilover suspensions and exhaust systems in both two- and four-tailpipe design with G-Power’s legendary DEEPTONE soundtrack – any customer requirement is compliable with the purpose of rising your 3-series from the masses. Every component is digitally designed with the original quality standards in mind. The performance upratings include the maximum speed delimitation for the factory-restricted engines.

G-POWER Bi-Tronik / D-Tronik Performance Software
More performance due to optimisation
Our technicians have carefully adapted the G-POWER electronic performance software Bi-Tronik and D-Tronik to the characteristics of the BMW engines. In doing so, our engineers can fall back on a wealth of experience of more than 25 years in the field of engine development; a daily growing established clientele confirms the reliability of the electronic performance enhancement of G-POWER.

The basis for the electronic performance enhancement of G-POWER is the fact that we, in contrast to the manufacturer, do not offer standard software full of compromises but a programme individually tailored to your engine. Among others, the parameters for the amount of fuel and the ignition timing (gas engine only) are modified, for charged diesel- and gas engines the boost level is increased additionally by our engineers in dependence on the product variance of your engine.

The electronic performance enhancement of G-POWER do not only achieve a perceptible increase in performance but also optimise the specific fuel consumption of the BMW engines without affecting their durability.

Product features:
- Quickly feasible performance increase
- Easily reversible modifications, therefore particularly suitable for business cars and leased vehicles
- Maintains all standard engine protection and diagnostic functions of the engine control unit
- Improved performance of the BMW engines
- Optimised specific fuel consumption
- Lifting of the electronic limitation of the maximum speed possible on request
