if you can get it remapped for about 200 pound it would be worth looking into, you would get really minimal gains on a stock set up my guess is 3-4bhp , but with exhaust, air intake and decat it will fix the air to fuel ratio and you should get more upto 9-10 (i might be wrong with these figures).
also if anything the perforamance aside you might make your money back from the efficiancy of the remap, it should deffinatly give you better mpg from complete combustion, better burning of the fuel.
