First Impressions, JB2 + UR Catless DP's

After a long day of school, studying, and installing the JB2, I just got home to tell you guys share my first impressions with the my new JB2 installed along with UR Catless DP's (which were already on the car).. Adrenaline is still pumping through my body (esp my hands), I can't emphasize how much better the car feels compared to my previous tune (SSTT). The power is smoother and the higher-end power is amazing, unlike the SSTT where its advantages are at the lower RPM's, the JB2 runs strong to the end. I can say that my rear tries break loose even quicker and the pull is an incredible feeling. I can also tell the difference in the amount of time it takes for my turbos to spool for I have catless downpipes.. With the SSTT, it was still enjoyable to eventually hear my turbos spool, but with the JB2, as soon as I hit the pedal, I can hear them, crisp and clear. Of course this is only my first (half day) day driving with the new tune, and it should adapt the more I drive it and the better it should get. But for now, these were my first impressions of the JB2. First impressions are the most important right?

Nice dude, reminds me of the first drive with DP's on my GIAC tuned 01 S4! I love that sound of instant turbo spool!

when i first got on it after i installed my jb2 i didn't feel much of a difference in power, but after driving for a couple minutes I gave my self whiplash with some 2nd gear pulls to 60mph. Also I was surprised how quickly it got to 85 from 65 in 6th gear. I wasn't even looking and oops there goes the speed limit. I really hope it does get faster after a few days of driving
