Smoke = wasted fuel & soaring EGT's. Save yourself the hassle, and save your engine.

As for more power, search around here...there's plenty of threads on the matter.

the 6.5 cannot handle smoke like other diesels, it will it will cause high egt's and melt it down.

if you are set on having smoke then just remove the vacuum line from the wastegate, you won't have more power but will smoke

These guys are right. Smoke = bad. You want to fog out the neighborhood? That's Cummins territory. you'll melt down a 6.5 pumping out black smoke. Then you'll be out an engine.

Black smoke does not = power. Black smoke = wasted fuel and your also throwing money away.

Giant clouds of smoke are not cool. A quick puff on hammer down accel that clears up is fine. People wonder why emissions are getting so strict on diesels, yet then get in their diesel powered (insert brand here) and proceed to puke black smoke everywhere. This causes the enviro-nuts to go and up go the emissions standards for diesel even more.

Furthermore, Anyone can make a diesel smoke. I'd rather use all the fuel available and make power with it, but that's just me.

Well, you've gotten enough (good) advice regarding the smoke so I won't continue the bashing.

I was able to get a little more performance out of my rig by putting in a drop in K&N filter and installing a TurboMaster (manually adjustable wastegate controller).

I recently also was able to delete my vacuum pump too. These are small $$$ improvements that do yield a little performance gain.

Like said before, Turbomaster, Exhaust, Intake Manifold Swap if you have a S code you want and F code(I sure as h**l do) then you get into reflashed ECMs these are the only reasonable ways to get more fuel out of your pump. As for more general performance you can actually get into the transmission to improve shifts and general power to the ground.

Like said before smoke=Fuel not being burnt. The only reason smoke is associated with High Performance is because people up the fuel for a chep upgrade in power on all mechanical engines a la the 12 valve Cummins and they dont upgrade to a bigger turbo. Unfortunatly the 6.5 cannont handle the amounts of fuel the Cummins can for reasons that I can explain but it would take another book.

Whew... sorry this was such a long post.

Very bad idea to hold the wastegate shut on such an inefficient turbo. You can easily overspeed it with the wastegate held shut. Not to mention the horrendous backpressure the stock turbo's have.

Wow! I just dont understand wht people want black smoke out of a diesel engine... Or any other engine for that matter. All it means to anyone who knowes anything about engines is... it It aint runnin right!
Yesterday i was going up a 8% grade that topped out at 8200 feet. I was in our 1/2 ton Silverado flatbed unloaded with a 4.8 6 cyl gasser. A guy with a Dog CTD tried to pull me up the grade. It was a joke. He had his foot deep into it, and was belching black smoke like cummuns do when they are over fueled. . I left him way behind and toped out the grade at 85. If he only knew he had his azz handed to him by a little Chevy 6 banger.... Ha Ha Ha!
Never been impressed with black diesel smoke. Maby a good puff when banging thru the gears......
But under a steady load NEVER!
To me when i see a diesel workin hard goin up an grade and nothin is coming out the stacks but pure heat waves.... I think. Sweet!

I have got to agree with you guys. The Sub will let out a very nice little cloud if I give it the hammer, but it clears up as soon as the turbo spools. Under normal acceleration, it does not smoke at all, nor do I want it to. I never knew that prodigious amounts of black smoke was cool until I started watching Youtube. No black smoke means that your engine is actually burning the fuel, not just dumping it through the engine.

Now say this with me: "One puff is 'enuff.'"
