I bought my 535 to be a "luxo-cruiser" daily driver with good gas mileage and intended to install a Dinan software upgrade, intake and exhaust as soon as they were available.......they said 2 to 4 months but that was 18 months ago. When I tire of the lag (every 3-4 days) I take my M5 out and play.

BMW and Dinan just reconfirmed to me last week that they have no software upgrade for the 535 so I am thinking of JB or the Hartge software from Turner (56 HP and 59 ft lbs torque) for $1300.

Anyone have the Hartge software?
