Either way i totally agree with Noel, probably more than 30% extra fuel use when you condsider you can make even more power/timing/boost which is only going to lead to added fuel consumption again.
I'd be interested to know how legally, retailers like Fueltown could sell you something that would corrode your tank over a period of time.
They are opening up their anus to some serious pain.
Side point - i will PM you about guest speaking @ our general meeting as you are Vic - we love hearing about products
