I doubt very much that the cable mod produced those results, there is just not enough power lost in the OEM-cables.

If for example you go from 16 to 18.5mpg at 100Km/h you are saving about 2l per hour. that's 19kW from the fuel, with 21% engine and 70% alternator efficiencies that would mean you had at least 2.8kW electrical losses in the wires.

The entire electrical load of a typical car is maybe a tenth of that.

2016: 128.75L for 1875.00km => 6.87L/100km (34.3MPG US)
2017: 209.14L for 4244.00km => 4.93L/100km (47.7MPG US)
