rubbish mate, this gets discussed lots on many motoring forums, yes years ago there used to be a company that had the market called superchips, that sold you an expensive piggy back to your ecu -
power increase starts off, with a bloody good service, plugs/oil then breathing,on some cars air filters, but I think this is a myth, a decent ,mesh panel filter regulary replaced is as good, as the most new cars have air mass flow meters and large non standard air filters just make noisy induction roar and can wreck these sensitive sensors and there not CHEAP, the bhp gain is questionable - removing catayltic convertors in centre sections and downpipes will transform a lot of cars as it makes it freeflowing and non restrictive, MOT time means chucking them back on, or just 1, or a secret tenner in the MOT's mans pocket to "forget" the emmisions test - free flowing back boxes, then larger injectors, larger bottom ends, uprated fuel pumps, biggers turbos, rerouting intercoolers, and then esentially remapping the ECU to take full advantage of the mods you've just made, so the cars driveability/reliabilty isnt comprimised too much -
Im sure what car you're doing it all on, but dont forget good brakes/uprated discs/pads and suspension setup are equally if not more essential
