G'day mate, haha that's pretty funny about the fuel. They sell bp ultimate here and the quailty would be close to as good as anywhere, just probly not in the wet season as hudmity gets to 3000%. I only fill up at bp on smith st in the city, that's where all the hoons fill up... from what ive been told I would defently reconmend you take your machine to get tuned by Keelan at "Pecky performance and dyno tune". Tell him Craig sent you, hes a good mate of mine. He even has a bf xr6 turbo with simlar power to you and run flat 11's in it. He loves these things. Not much has happened as far as turbo'ed falcon cruises but I see theres a few guys kicking around in this forum every now and then. With the heat up here, expect to feel the power drop, and see a big differance on the dyno, as its a killer this time of the year all the way untill the dry season next year. In the dry we get nice crisp cool nights down to as low as 12 degrees and bugger all hudmity.
