In my opinion i would stay aways from ITB's, especially if you dont know what the hell your doing. In my observations of my cousin who is very good at tuning and all that good mechanics stuff I consider them a pain in the ass. Yes the gains are awesome but only with the right tuning and unless you know how to tune them the maintainance bill adds up. Boost is cool but you have a 10 year old engine in your car and as far as i know its not rebuilt or anything so that might be a little dangerous.
