Sounds like this knob at work, hes like 30 something and works part time as a mechanic. He knows f**k all about cars and recons his clio rsi is the nuts. He thinks that getting it chipped will add 20bhp. He knows nothing about anything, he tried explaining to me about how the chip controls the ecu and could therefore deliver more fuel to the engine thus making it faster. I didnt even bother trying to explain to him that engines can almost have as much fuel as they want but its their breathing which limits their potential horsepower. He doesnt even know what a clio 16v is, I tried explaining what one looks like with the bonnet vent and arches and stuff, but he kept saying that i was talking about a williams and that I was wrong because "he was a mechanic"
