Hi All, I am aware that most remap services use a pre-developed file and the hand-held device or technician just upload this file onto the ECU. So with that in mind I started to put together a list of providers, trying to see how many use a common file: SuperChips https://www.superchips.co.uk/search?make=22&fueltype=1&model=82&variant=2031 +54hp +51nm (Requires 200 Cell Cat apparently) Quantum Quantum Tuning - Chip Tuning | Engine Remapping | ECU Programming | DPF Solution +53hp +50nm SA Tuning SA Tuning - SA Tuning Remap | Chip Tuning | Engine Tuning | DPF removal | EGR delete +72hp +55nm (Custom Dyno)? +53hp +50nm (Hand Held) EuroCharged / MSL Site Offline Stock Car??? +100hp +60nm (headers?) Celtic Tuning Do you own a Mercedes Benz C Class? Gain up to 15% of power! +66hp +43nm Litchfield C63 AMG (204) | Litchfield Motors +40hp +20nm JR Tuning JR Tuning UK - Mercedes C63 AMG Remap Tuning - ECU remapping, C63 gearbox remap, C63 P31 Remap +41BHP +48Nm Eco Vehicle Tuning Eco Vehicle Tuning +66hp +43nm GAD Tuning C63 AMG tuning +57hp +65nm CKS Performance AMG C63 ECU Remap +90hp +51nm (Stock?) Avon Tuning Mercedes C - W204 - 2007 > 2010 Remap & Tuning +53hp +50nm The ones with 50hp/50nm look to all use a similar map provider... Are there any others to consider? (aside from custom dyno maps). Also some figures are questionable, I guess they are from modified cars e.g. cat deletes etc.
