Have a look at this 5th Gear youtube video, it'll give you an idea of what to expect>>>

Just spend your money on decent fuel instead. v power etc, that's the best way to get a bit more go at the top end from a modern performance engine. (higher octance and other additives don't increase power directly, it just means the engine management can advance the ignition further at higher revs without pinking thus helping to obtain more force from each combustion) The 335i's and my old 330i seem to run much better on 98ron, v power more than others, than 95 (mine feels like its full of treacle if I have to put 95ron in it). The knock sensing on modern engines is very sophisticated and will allow the ECU to run right at the limit of detonation to get the optimum ignition angle without being backed off due to detonation)

Saw some bloke in brand new 991 turbo at the weekend, putting in boggo unleaded, then spending 2 minutes holding the gun upside down tapping out the last drops, lifting up the hose above his head as if he was tipping fuel out of that part too.....numpty.

But he was wearing a leather waistcoat with nothing underneath. :-)
