Don't fall for crap that claims big gains for a low price, especially on ebay. Usually won't happen, waste of money. Hell if they worked... we'd all have one.

 

LOL, thats because that is what the commercial tells you. They need to make up something that sounds smart so people go 'Of course, that makes so much sense!'. Unfortunately its bogus man.

As for 2.8 upgrades, you are a college student, shouldn't you be blowing your money on beer and private strippers for the frat house partys? C'mon man, I know the Audi is cool and all, but where are your priorities? You can drive a modded car later when you get a job. You can't get that much ----- in one place ever again once you leave college. Have fun . . . . ..and wrap it up.

 

Make sure you have good spark plugs and a clean air filter. lol !
