Burning Rich?

[wyoramsrt-10]

Seems like I am still burning pretty rich after the flash. Truck still runs great and is faster than pre flash. But every now and then when I mash the go pedal I see a cloud of black smoke. I am guessing when I am driving normal I am getting some soot built up in the exhaust pipes and just clearing out the excess when I romp on it. When I run it hard I don't see the smoke. Just an occasional smokescreen after some easy drivin. Any one else have this happen?

the flash increases the fuel being fed to the engine, and at cuise it may hav a tendency to "load up" a tad, and when you WOT it, it burns out the exxcesse fuel

That's what I figured. But figured I better make sure.

If you are not running a catch can, you will get some oil blow by into the intake, usually this will be noticed on the deceleration side though and will be blue.

Even with my blower and tune, mine will do that...
