Remote,<br><br>Only you can answer whether its time for injectors. I don't know anything about your banks stuff to know what you *could or should* do.<br><br>If you're getting your EGT pretty hot, and If you don't already have a fitting on your turbo that keeps the wastegate shut a bit longer, which gives higher boost pressure, thus lowering EGT, I'd at least pursue that. Just to lower the EGT a bit, not necessarily for more power.<br><br>I'm sure there are things you can do, I'm just not so familiar with your truck and am no expert.<br><br>Personally, I'm making about 295 / 650 to the rear tires. I get a little smoke if I get on it before the boost comes up. But it goes to a haze, then clears, and give me real good power. All for $660 and some bargain shopping!<br><br>- JyRO

 

Remote, your fine. You don't need to up the injectors just because you dont see the smoke. Smoke is nothing more than unburned fuel going through your exhaust. That's it. The less fuel you have going through your exhaust, means the more fuel your burning in the cylinder. The more fuel your burning in the cylinder, the more power your getting. ;D Clear as mud?

 

Dude MUD isnt CLEAR!!!!!!

 

<br><br>Gary, you &amp; I must be brothers. Or at least, very similar in some ways. Because my expenditures on power mods to this point has been pretty small.<br><br>That's because if I want any more power then what I have now, I not only have to pay for whatever the mod is, but I'm looking at a clutch too. And then I'm looking at what I consider, serious money. As it is, I've spent *only* about $665 to get used RV275's, an EZ, and a MEK. I still don't have gauges <br><br>Yeah, I know you guys are shocked, but I have some other expenses I feel is more important right now. And this is why I haven't gauged yet: In stock form, this truck doesn't have enough power to damage itself unless you do something really *not so smart*. Like lugging with your foot to the floor for a long time pulling a heavy load up a hill.<br><br>But from my research into what I'm running, I should be running cooler than stock (boost elbow, MEK), and if there is a significant hill that I have to pull toting my 5'er, I run 5th at about 2,500 rpm with pedal left and lots of boost. So I know I'm not abusing it, and gauges will be coming.<br><br>So Gary's right, h.p. is just a matter of money. And I've got enough h.p. to the point my truck get's the job done very nicely. Any more money spent (except gauges) on my truck and it would be a waste of money, for me.<br><br>Remote - I think there's quite a few things you could do to your truck to make power, and not too expensive to start with. For one thing, on 12V trucks, there some kind of &quot;wheel&quot; or something on the P7100 injector pump that can be altered which would give you plenty of smoke ... FOR FREE. You could find out how to adjust that until you're getting some smoke. Once you're getting some smoke, if you can't tell that you're making more power, then its time to look elsewhere.<br><br>It seems to me like, turning that wheel to get more fuel, and adding a boost elbow to your turbo for more boost should give you more power, for real cheap. But I'm no 12V expert ... heck, I'm no expert at anything. I know only enough to get myself in trouble.<br><br>- JyRO

 

The mixture for best power is one in which there is a surplus of fuel--in other words, every oxygen molecule has an available fuel molecule to bond with. You can produce no more power than that until you introduce more oxygen. Some fuel molecules will go out the exhaust unburned.<br><br>The mixture for best economy is one in which there is a surplus of air--i.e., one in which every fuel molecule has an available oxygen molecule to bond with, so that every fuel molecule will be combusted. Many oxygen molecules will go out the exhaust unused.<br><br>I doubt if very many people have reached best power mixture in a diesel. The fact that there is smoke is not so much an issue of lack of oxygen as it is matching fuel with available oxygen, since most diesels operate at something like 35:1 at WOT. A gas engine wouldn't even run at this lean of a mixture, and this is as rich as a stock diesel ever gets.<br><br>Consider all the people who put bigger injectors on their engines and THEN dump in propane, too. The propane wouldn't do anything unless there was air available, even after the extra fuel the bigger injectors put it.<br><br>
