ive got full exhaust system and airfilter i just wanna get a good lil remap on it, can i just take it to a place to get it remaped or do these cars need a different ecu to be remapped? what about a bluefin chip as ive only got a few mods? and also what other mods can be done on these to get most bhp without getting bodies and staying n/a... thanks for your help guys
