Hi,
Im from the UK and we have tesco 99 RON fuel - i normall use the shell V-Power 98 RON but due to my location when low on fuel used the tesco 99 instead. After getting through a quarter of the tank the car seems to be lacking in power and doesn't have the same responsiveness as before.
I am guessing it is due to the new (different) fuel im a using as its always been fine when using Shell.
Can anyone confirm wether the ECU has reduced some degrees in the ignition timing due to knock or for some other reason. As soon as the tank is approaching empty im going to stick to Shell V-Power.
The car has a Cobbs Access Port Stage 2 base map and TCM LV2 plus aftermarket exhaust.
Thanks
Ben
