Just installed v2 this morning, so far I love it. Shifting is even smoother now between all gears. I always botch the 1-2 no matter which tune I have, but it already seems better/easier to get right in v2. The whole tune just seems more refined.
I have the "crackle and pop" version running, and it is very subtle but still noticeable at low speeds with the stock cat. I'll probably just switch to the normal tune since the stock cat mutes it so much anyway.
Overall, very happy and can't wait to unleash the car and test out the tune more. It's so hard to have to hold back on my commute!
