No, you wont have to mod the fuel on the kind of setup your after. Personally i would ditch the filter and put the standard airbox on then take yourself to a good tuner and have the car setup as standard and see if its up to the job.

If so stick the chip in, upgrade the intercooler and run about 13psi of boost. With a good setup your fuel will be fine but expect between 160-170bhp depending on engine health.
