Guarantee and Insurance
Insurance
More-MPG.co.uk offers peace of mind where ECU tuning is concerned. In the unlikely event you experience a major concern directly attributed to the file remapping process we’ll be there to help.
More-MPG stands apart from other ECU tuning providers as the file writing services provided to us by our technology partners, Viezu, are independently underwritten. Viezu are independently audited twice per year to ensure they continue to meet the quality standards expected of us.
Money Back Guarantee
More-MPG.co.uk offer a seven day money-back guarantee so you can trust us to be there for you. We often extend this period for economy tuning providing you have documented details of fuel usage before and after the re-map.
Find your car using the boxes below and the fuel economy improvement will be displayed (tick economy check box). Almost all European vehicles covered. More Japanese models will be released Mid-April.
