That’s what I was thinking too. The EPA tests at certain speeds in a certain order. On a Dyno at a performance shop, the speeds would be much higher and in random order. Also, the duration of engine operation would be different from the EPA tests.

Yes, sub-10 minute runs used to be pretty mythical, but that was the old Pike’s Peak when it still had dirt sections. Now that it’s 100% paved, 10 minutes is more easily obtainable. Regardless, 10 minutes is still crazy fast!

I saw the same thing on my MS3. It really wakes up once you put an SRI on it.
