My Sierra Ext Cab SB LBZ (5" turbo-back MBRP, Fluidampr, BD exhaust manifold, Airaid, ATS Five Star) is untuned but very quick. One of the things I like best is that it doesn't create localized IMC (instrument meteorological conditions) when I blow past other traffic getting on the freeway (for example). Anyone know of any tuning options that will add smokeless power to the truck?

A good tune done with EFI Live will not smoke. Get in touch with the tuning experts for your trans safe tune.

Low smoke tuning is one of my favorites. Of course the race stuff smokes, but it's a pride thing to blow past someone with just a wisp of smoke while others just lay down clouds.

My Superchips Flashpaq is smokeless on all settings.

I've been running Kennedy's tunes for a couple weeks now and have yet to see smoke in the side view...

I'm basically smokeless with an EFI tune from Fleece Performance. love it!

clean and quick :chevy:

I love blowing past people dumping smoke....maybe im weird but to me thats the best
