I noticed that on the version 1 Cobb, there is an update labeled 1.30 for Stage 2 91 octane. Has anyone gone from the very original (1.1 or something) to the 1.30 flash and noticed a difference in performance? I have an 04 WRX with 38,000 miles.

Yes I did that a while ago and there seemed to be an over all improvement in drivability, maybe even a bit more power sooner.
