Well I'm guessing by your avatar that your the lad who bought bens chaser so I also assuming that he would have given you the rundown on the car including the fact that weston mapped for super unleaded which in the uk is 98/99 octane.
It would be very unwise to have run that car in anger on anything other then the fuel it was mapped for. If topaz is e5 thats great for anyone with a standard ecu'd jap car but for a car with a custom map for uk super, e5 would be no better then 95 petrol as e5 has such differences in burning and temperature characteristics.

But if you know all the answers sure the thread was pointless!

Never said i knew the answers was just posting what i have learned!! I value your opinion and thank you for posting!! Ive decided to get her mapped to cope with the shite Fuel over here!! Was just looking for an alternative for Punchestown!!

Thank u all for your help!

Like a few others have said dont run anything if its not mapped right unless you have to. And then keep off WOT and no boost.

What ever fuel you get it mapped on will make power, higher octane reduces knock which will let you advance the timing more and will help give you more lovely torques.

If your going big power and want to run e85 you will have to spend a fair bit on your fueling set up.

use what ever petrol you can get easiest and get her mapped right, being reliable is the most important thing.
