I've seen a mk3 16v on ebay saying hes got 190 bhp. Thats got jenvey throttle bodys, itg air filter, mild high lift cams, gas flowed head, stand alone ecu, exhaust system, veiner pully. I can believe that.
I was a member on saxosportsclub and with a set of cams, throttle bodys, air filter, exhaust and a remap you will easy see 170bhp from 120bhp.
