After some advice
I run a GSI MK4 with the full CS4 package from courtenay so basically everything has been done and is running around 287bhp 330lb of torque.
Want to know what kind of miles I should be getting to say £20 of V-Power priced at 102.9. Or if you know what mpg i should be looking at if its easier?
Not sure at the moment if it's over fuelling. Thought it may have been the AFM but not showing any other signs of problems on the engine management system.
Can anyone let me know what I can try or answer any of the following questions?
