hey you will definatly! not oxwagon to rocket but it will def. be worth it!! by all means i wouldnt use anything other than DASTEK UNIQ chip! 5map setings example : 1 for economy 1for track days 1 for towing etc..
bluetooth option to change between map settings using ur mobile phone! you can even have a limmiter on say 120kmh for when someone borrow your car or it goes in for a service!
and it 100% universal so if you sell your cabbie use the chip on your next car! if it can power a twin turbo gallardo on stock ecu im sure it will do your 330I good!
you can even use the chip to engauge NOS and regulate it between gears example 30% nos in 1st 60% in 2nd and 100% in 3rd! My tuner also good buddy of mine installs and map the chip for R3000
you can even remove your lamda sensors or oxigen sensors after you installed the chip! then you can use avgas or any other leaded fuels with no shit! i used to change the sensors every time i used avgas on track days now i just use what ever i want!
and get your hands on a BMC replacement filter!! with chip exhaust and filter you can look to close to 145 kw on the wheels in a rough estimate!!
