Thanks for the refreshingly unbiased review. People severely underestimate the power of placebo. There are entire industries run on that stuff. Human beings are very unreliable detectors, and any comment like "I definitely felt a difference", whether it is about an ECU re-flash, or a pure silver speaker cable, or a $1M violin, or a $100 bottle of wine, etc etc, doesn't mean jack without reproducible measurements to back it up.

I would personally pay that much money only to fix up the throttle delay, as I find it very annoying when I try to heel and toe. But I'm not surprised the power gain is very modest.
