    E24 635CSi Turner Motorsport Conforti Performance Chip
    Part #: E24635

    The M30 3.5 inline-6 is a torquey motor, however it could be a little more powerful in the upper RPM range. With a Turner/Conforti Performance Chip power is boosted at all RPM with over 20ft-lbs of torque gain at only 2000 RPM. This chip was tuned on the dyno to yield as much performance from this engine as possible and still maintain its strength and durability. Jim Conforti tuned the fuel and spark maps to take advantage of 91 octane gasoline.

    Turner Performance Chips provide the ultimate in performance advantage! Adding a performance chip to your BMW is the easiest and most cost effective way of increasing BMW power, torque, and performance with NO DOWNSIDES. Through years of BMW performance tuning, we are able to maximize power and torque gains for 91 octane fuel used in North America. By making changes in the ignition and fuel maps of the DME we are able to optimize performance with no side effects or compromises. Other changes will make your BMW smoother and more responsive than when it left the factory. Our chips have a lifetime warranty and a 30-day satisfaction guarantee. If for any reason you are not fully satisfied with the increase in power and overall drivability you can return the chip to Turner Motorsport for a full refund. Chips are supplied with detailed instructions and are user-installed in about an hour. See below for specific information that we may need from your BMW model.

    "I went with the Conforti that I bought from Turner and am very happy with it. There is no noticeable (to me) change in fuel consumption. I have slightly better pop in lower gears where , gawdknows, the car really needs it and the car certainly pulls faster and stronger at the top end." - Taylor, Montreal, Canada.

    "I have just installed the Conforti/Turner chip, actually increased my gas mileage by 1 mpg, but the power curve is much better and the movement of the point in the RPM bad where the engine limits itself is so much nicer. I am very happy with the change." - Rick, California.

    "I tried Dinan and BavAuto…I like Jim C's the best." - Joe, Connecticut.
