I just updated from version 2.066 map for 91 octane/UEL headers (OFH) to v2.069. Wow! I can actually feel a noticeable difference. From low mid-range to redline there's clearly a smoother, more progressive increase in power. My car also seems quieter cruising at highway speeds, is that possible? On the other hand, I actually managed to kill it at a stoplight, which I haven't done since the first week I had the car. Seems like its a little slower to rev from idle, but that's just a little retraining of my foot.
I can't believe how much improvement the OFT/OFH combo made, and it just keeps getting better! Thanks for all your work!
