Hi Mark, Please feel free to add this to your website – Kudos.
I was already happy with my 2003 540i, but being used to high performance vehicles I decided to have Mark design a flash for my 540.
The flash is used for 93 Octane and although I haven’t dyno tested the car, the seat of the pants response is immediate, crisp and linear
torque in the middle of the RPM band, right where it should be. This translates to a constant surge of power all the way to redline,
which –by the way, was raised an additional 500 at my request. I am very happy with the transformation of additional power all while
remaining civilized as a four door family car.
Mark is a consummate gentleman to deal with and can accommodate a tailored flash/chip at your request. You will not be disappointed.
