Once the ECU detects any knock at all it begins decreasing the multiplier.

What this means: the 12 hp gain after resetting is all intake. If the power was causing it to run lean or detonate the ECU would pull timing and that 12 hp gain would not be reproducable but it was which means that 12hp gain is safely achieved.

Thanks bud
Ok...dyno it again in a week (or 30 miles, whatever) and see if the ECU has learned around the new intake.

I never said the K&N doesn't help - I had one in my WRX and it seemed to smooth out the power band.

The temp/humidity is going to be different, yes. But it changes every day. You're never going to get the same numbers on a cool day as a hot day with the same setup. What's your point? Are you only going to drive when the conditions are the same as the day you did your dyno run so that you can say "I have +12 HP today!"
