i don´t see it as negative what he says. it is just about not believing in those chips. so don´t i. those chips, without any other work that really REQUIRES the chip, it is useless. i have tried it already and the result was higher gaz consumption, nothing else.
get some cams, exhaust system, pistons maybe....do the real deal and then a chip does a job cause those mods require another engine software. for a stock engine, a chip is a joke.
a totally different story of course are diesel engines. with them a chip can perform a small wonder. that type of engine really has some hidden power to unveil...
the magic bean hint actually is pretty nice and funny.
