Hey Dazza, I started mods on my 07/07 BF ZF after 1500 km. if I could have it again, I would just do CAI and panel filter,Injectors and a massive tune; and that would be it, I wouldn't do any thing else at all. Except maybe upgrade the brakes, but that would be it. Oh, I'd probably do the fuel pump as well, but no more. Exhaust, maybe just the exhaust. And; the wheels, I,d change the wheels to I think. and then get it crawling on it's belly with some SSL's. BUT that's IT! Unless. Unless I upgraded the Intercooler, Mmm, I,d probably do that too! HELP!!! What the hell is it with these beasts. But I will say the Fuel economy is quiet good at 48 liters per/ 100 KM. Cheers. (Excuse me, do you know where they sell 98 RON, in this area.)
