MPG after tune

[Alex117]

Hey all,

I noticed an increase in MPG after a stage one MHD tune and DO888 intake. I am considering OPF delete and maybe a decat. With this would also be a stage two tune.

So a question what mpg would you expect or what do you get real world with that tune?

relevance as I fully appreciate it’s a 3l turbo petrol car is I do quite a few miles in it for work.

appreciate y’all

Post-custom tune, Pure 800 I'm looking at 28mpg combined, still 30+ on the highway. It really depends on how hard you drive it.
If you sit in sports mode 24/7, you'll obviously have lower mpg.
If you shift and don't let the motor sit at 3,000 RPM, you'll have higher mpg.
If you run higher Ethanol content fuel, you'll have lower mpg just due to additional fuel being required.

Thanks.

working out the maths of US VS UK gallon this sounds about right for me.

I’m looking to stick to 98OCT fuel
