Thought I'd try V power.

The thick get plotter !
So are we now saying the dudes who say they can feel and or do notice a difference that their bikes have unbeknown to them had the timing modified 

Well I'd heard that an ignition advancer could make the bike feel better or whatever so figured I'd give it a punt as they aren't expensive. As it turns out, it did so I never took it off - if it hadn't of worked I would have just removed it and taken the financial hit.

With V-Power though, the car definitely gets some better MPG

What sort of cage are you driving?  Have you checked the owners manual for recommended Octane?

As for the car (MG ZS 180) - I've never bothered to look at the recommended Octane fuel. Its naturally aspirated so didn't consider this before hand but a little research says that it is tuned to run on 95 RON apparently...

People on the MG ZS forums reckon that you can get up to 200hp (+20-25~) by remapping the ECU
