But you have actual mods. And your car is actually quick. You didn't buy a muffler off eBay for 15 dollars and claim it gave you 25 horsepower.
After thinking about the "polishing a turd" statement, that would apply more to modding a Cavalier or the like. In this case it's like taking a fine piece of crystal or a work of art and then rubbing crap all over it and claiming it's good because it took a lot of time to rub all that crap everywhere.
