@Tully1980 I fully agree with what you have said that it does not have to affect your fuel consumption.
This is a common quote from tuning companies "Dependent on your driving style, this software will deliver like for like fuel economy in 'normal' driving conditions."
If you drive the car in non aggressive mode then fuel economy should be roughly the same however if you use your right foot then there is a bug in the car and the fuel evaporates and mpg figures go down (No errors are showing on my OBD11 Scan or VCDS for that matter).
On my last track day I think I went down to something like 12mpg but it was worth it.
Yes, I’ve noticed more of a drain if I’m driving aggressively, but overall it’s stayed the same.. I think my long term mpg is hovering around the 33-34 mark which isn’t too shabby
