Just curious what your feedback/driving impressions were. I've been running the 91 octane tune for about 3 weeks now and am really enjoying the extra power. First thing I noticed was that is was definitely boosting more in 1st and 2nd gear. I'm using DashCommand on my iPhone with a wifi OBDII adapter to monitor boost and other parameters (intake temp, torque, etc.) Not really into the data logging thing yet but its nice to see boost and intake temps. I am running an Injen intake and a CP-E motor mount but am otherwise stock. I really only get to open it up when I'm merging onto the freeway, but this car really rips! I drive pretty conservatively but really enjoy the extra passing power and the 0-60 performance increase. The trade off has been a slight decrease in economy but that is completely acceptable. Overall, extremely happy with the Livernois tune.
