Not everyone has the means to custom tune every engine they have. I don't disagree with you guys, I just think there are two extremes to the situation; while all the "smoke out" guys are on one end of the spectrum, some of you guys take the complete opposite extreme, when I think there should be some middle ground.

Heres my challenge to all of you: If you really put into practice what you preach, post a video of your truck. From a stop, WOT, and I don't want to see any black smoke. Now the rules are you can't go out and tweak your truck truck to where its a lag pig (taking it back stock, turning pre-boost fuel down, etc.), I want to see it run like you have it every day of the week. This is a diesel performance forum and I expect to see performance tuned vehicles, stocks trucks need not reply.

 

Mine will smoke if I do that, but I try my best not to. I recently adjusted my kick down cable to help eliminate more smoke. Once I'm all spooled up, I can't even see a haze while at WOT. My truck is not a junker, and I'd like to think I'm rather in tune with engine tuning. Pun intended.

 

So, heres my 2 cents (which may actually be worth less)...

Why do you think there are such high emmissions standards for new trucks? Why do you think diesel trucks have to now get smog checked? How do you think UREA injection came about? etc. etc. etc.

The answer is very simple. While blowing black smoke around seems innocent enough, like it or not, it makes us that drive diesel trucks VERY noticable. And this is precisely why the EPA has cracked down on both emmmissions and the diesel performance industry. Will they shut it down? Likely not, as there is a lot of money on the line and the engineers will just work around the rules. One thing is for sure - the EPA does enjoy making it difficult for everyone involved - from the vehicle owners right to the engineers that design the performance products.

I have been driving diesels for awhile now - long enough to remember it wasnt even considered "cool" to have a diesel. The reason I went to diesel was driving long distances, and the durability and reputation of the Cummins engine. I didnt buy a truck just because it could "roll coal" - which so often happens these days. I miss the days when the kids were in ricers instead of diesel rigs.

Its pretty sad what has happened to diesel performance...and you can thank the smoke blowers for it. Im not preaching but it is what it is.

How nice would it be if you could right now walk into a dealership and buy a 12V Cummins instead of the junk trucks they are selling now?

Just my opinion.

 

I agree with you dr. Evil I'm young 21 I was 19-20 when I got my first diesel it crossed my mind about smoking intersections out but once I got my first diesel and got on these forums I realized I wanted POWER, not all smoke.it irritates the he'll out of me when I see some young guy with all his friends driving a nice pick up that more or less his parents bought and their laying the smoke and romping on it at every stop.I always liked when a kid would pull up next to me and make some smoke cause I'd just lay into it a leave him in the dust with minimal smoke coming from my exhaust

 

I also forgot to mention that its not only diesel pickups. the trucking industry has also been required to clean up their act as well.

 

Off Road construction as well. They are forced into Tier4 as well.

 

epa has been doing the clean up for years. they first started on gassers. now they are working on coal fired plants.

 

This is exactly what I mean! All of these guys try to say that if your truck puts out any amount of smoke, under any circumstance, then you are a complete idiot and don't know how to tune a truck, and it pisses me off!

I think its not only good tuning, but also knowing how to drive your truck

It got so bad that CAT stopped making a lot of on-road engines, at least in medium duty applications.

And Dr. Evil, referring to your earlier, longer post, I agree 100%.

 

They don't have to. Its the customer's duty to research the tune they are buying to make sure its a reputable product and their hardware can support it.
Mechanical engines cost almost nothing but time to tune correctly.

The driver is 1/2 of the "tune". A driver should be knowledgeable and smart about how they drive. If you've got a fuel-heavy tune and laggy turbo, it should be a "no-duh" that you shouldn't mash the throttle from a stop.

Not true.

a 12v cummins with the fuel up there and a single charger would be nearly impossible to run without smoking.
