Mercedes C63 AMG DG520Review of engine remapping the C250 CDI by GAD Tuning LTD
The Mercedes C250 CDI with its 2.1 twin-turbo CDI 4 cylinder engine and reduced-torque-slip 7G gearbox is geared towards economy executive saloon. However here at GAD Tuning LTD an E250 CDI remapped will produce an extra 40 bhp and 55 nm of torque just form ECU remapping. GAD’s bespoke remap raises boost by 3 PSI and peak torque 1500 rpm to 3700 rpm giving excellent power delivery as well as massively increasing throttle response.

We currently have our very own C350 CDI running over 300bhp and 750nm of torque while maintaining fuel economy and is used as a demo vehicle, running the EDC17 CP46 platform of ECU means anti tuning protection so the ECU must be bench flashed.

The Mercedes C63 AMG also benefits massively from our Bespoke Mercades C-Class engine remapping software, the engine as standard is highly detuned compared to other models, this means through our Mercedes C63 AMG Bespoke ECU remapping software we can achieve an extra 60 BHP and 65 NM of torque over the standard vehicle. We can also offer supercharge kits being  from Weistec as GAD Tuning are official Weistec dealers and upgrades along with custom switchable exhausts, long tube headers and performance air filters. The exhaust note completely changes after our bespoke ECU remapping is applied along with much better gear shifts and huge amounts of throttle response.
