The quoted gains on the website are based on typical dyno tests. The dyno is pictured on page one (it's a bosch, floor-installed). I've asked for some plots and have not heard back yet. I've asked some other reps to see if anyone has plots as well from a customer car. 3rd party tests are always the best IMO so that is why I linked to the other thread.

There is a 30-day money back satisfaction guarantee on the chip. You can be returned to stock and get a refund (less labor fees) if you are not satisfied.

There is a shop 10 min from my location for those who wish to baseline and re-test, it is $75 for 3 pulls with AFR. I have an obd-scanner that can be used to collect speed/time data, in-gear acceleration times, etc. for those who wish to log some data after the installation.
