should i buy this? http://cgi.ebay.com/ebaymotors/AEM-a...QQcmdZViewItem or this is just a piece of crap =/.

 

Are you installing a performance cam as well?

 

It helps (not a lot, but it does help), it's lighter weight and if/when you get a turbo or oversized cam etc. it works great for fine tuning, for $50.00 or so I'd buy it if I had the money especially if this is a project car.
