OK I have what is probably an unusual question I bought my self a cupra 300 4 drive and the previous owner had it stage 2 tuned with a 3 inch miltek exhaust system and possibly other parts it apparently make near to 400 bhp now but on normal driving I am lucky to 30mpg so can i get it downtuned a bit for better mpg or is there an option to vary the tuning so i have economy in drive mode and power in sport mode or do i have to put the car back to original parts. just trying to get an idea of my options. Thanks in advance for any advice
