I have his agg. tow, street and extreme street. I ran the street for a while when I first got the tunes. It's nice. Got alot of power without the smoke and you can still pull up to I think it was like 10k. Then I put the extreme street in and wow! Love it! Thats the tune I leave on all the time unless I'm towing. When I get studs I'm gonna get the extreme race. Can't wait!

my vote: extreme street. i run it with stock bolts as my daily. i ran the street for sometime. pretty smooth tune. extreme street is easier on the fuel gauge. well, as long as you keep your foot out of it.
