Mercedes GL450 ECU Flash Makes V8 Bi-Turbo a Beast

The latest 2013 and up Mercedes GL450 features a 4.6L Bi-Turbo V8 with 362 horsepower to the crank.  Not bad considering it also puts out 406ft/lbs of torque.  But to make this soccer mom machine a pure brute, the ECU flash will get you almost up to what the GL63 produces of 549hp.  This ECU must be bench flashed which is quite the process.  The ECU has to be removed from the car and split open so both sides of the circuit board are exposed.  So besides paying for some difficult labor, you get our specialized service of ECU tuning the GL450 to a gain of about 140hp and 170ft/lbs of torque.  This makes the GL450 a totally different animal driving it.  If interested in getting this ECU flash for your Mercedes GL450, visit here.
