guys i'm interested in modding my s and would like to get your input on these three compnaies, revo technik http://www.revotechnik.com/index.aspx

awe tuning, and evo ms which is known to most of you guys.

any one who had installed their products and have hard numbers hp/tq , 1/4 mile, 0-60 and willing to share would be appreciated.

also any magazine articles that reviewed their products and tested them would be great.

presonal impressions are most welcome.

thanks to all.
