Congrats on the new power mate, that's a great result from the pulley change.
Thanks for your comments on mine, like to keep it as a wolf in sheeps clothing as it helps to annoy Civic Type R drivers

... which with your new power you'll be doing too
Mine often gives out a bit of black soot after a run on the dyno and its nothing to worry about as its better to be a bit too rich than too lean

It's because you've been giving it beans on the dyno then, taking it easy and giving it beans again so the car probably just chucked a bit more fuel down the pipe as it woke up to your right foot
