where did the black cloud go?

With my drag comp on 5x5,mach 4's and an htb2 shouldn't I still blow a good cloud at 2500 rpm?
On the dyno at 2500rpm my smoke clears out completely. The egts still climb(1600+) boost don't drop and I still make power so where does the smoke go?
I'm not complaining just curious.
If I can clear out the 4's maybe its time to try 5's.

Thanks Mooseman

I have a buddy who drag races his 02, M4's Dcomp, and an equivalent turbo his smoke is cleared up by the 60' line. M4's burn pretty clean with a decent sized single.

i say at 2500rpm's your boost is high enough to NOT allow a black cloud of smoke to be produced. now at 1400rpm's it might be a different story.

"...I still make power so where does the smoke go?", well the power is the result of the fuel burning in its entirety and hence minimal smoke. smoke = untapped power, its just waiting for more air.

sounds like a good combo, just needs a little more air for the EGTs...if thats of any concern.
