as mentioned by several mechanics.
i got told by one .. a customer had a xr8, exhaust/extractors and then got the chip, he didnt notice any difference and didnt even get more power.
unless you modify your cam, or have exhaust+extractors on, you people are living in a fantasy world
a chip will NOT give u 10kw, my ass it will, i'd like that in a dyno reading before anyone says that.
unless theres proof, i personally think its a crock of shit.
engine mods do a whole lot more then a chip.. changing your diff ratio, brass clutch, camshaft, extractors, cold air induction, mandrel bent induction.. etc etc etc.
10kw out of a chip, pffffffffffffT :MUha:
theres my 2 cents.
