Had to go straight to work so havent had much time to really try it out. I took the long way, then hopped on the freeway. even though I have to get off next exit. Seems to have improved overall speed. Cant say much more than that at this point. I have a 17 hour road trip tomorrow. So I'll def have lots of time to review it.
What drive mode are you guys using while the jb4 is on? I was running custom, which is sports engine, comfort suspension. It seemed like the car was always 1 gear too high when I needed to step on it.
