Decided to downgrade from 75hp DDP injectors to 45hp DDP. The guy at Dynomite said they smoked considerably less.

My question is..... I quit running the Hypertech because it just made the smoke problem even worse. What is available in tuners out there where I can just adjust timing, and eliminate defueling? I would like something I can "tune" instead of just downloading.

I have installed a few Diablo Power pucks, and see no major smoke like the Superchips and Hypertech put out...Just my .02

An Edge Juice, Drag Comp, Quadzilla Adrenaline all will give you in cab on the fly adjustability. Down side (if it is one) is that you have to tap the pump wire.

Smarty is another hand held option. It gives you 9 programs. Half with timing, half without. All w/ fueling enhancements.

Pretty much all power adders are going to give you low boost fueling, which leads to the smoke. Injectors just tend to amplify it.

If you add a turbo upgrade to the fueling enhancements ( Super B, S300, Aurora 3000) you will reduce the smoking considerably and lower EGT's..

In fact, if you bought a turbo, you could leave your 75's in and run the programmer and get much less smoke.

Darn.... The whole reason for the DDP's was that I had an injector stuck open, found a screaming deal on the 75's. Almost wish I would have gone stock. DDP was cool enough to allow me to swap down to 45hp. The ECM thinks I have stockers in there, and shoots the injectors like they are stock... all the while I am dumping a higher percentage of fuel at all times. The boost only compounds the problem when the map sensor gets a bar reading. Do you think there is a way I can fool the ECM into dumping less fuel? (resistor on map etc?) I have a hard time with these "tuning" devices, they seem to just do what the aftermarket company wants them to... I sure miss rom emulators on the boosted hondas, and for gods sake I miss the 700cfm on my 1971 Chevy. I would love to "crack" my Hypertech!:hyper:

Fact of life with these trucks. There are no true tuning things out there for the cummins. The adrenaline is very close though. Especially once quad unlocks the tuning software on the pulse monitor. But all of the programmers/boxes add fueling all the way around and fuel without air in these trucks makes smoke. And a bigger turbo is not gonna help your low end fueling problem. It'll actually make it worse due to the fact that it will spool slower and not provide as much air down low as your factory turbo will.

Is there a way to put a resistor on the map wire that will limit boos referenced fueling? I read somewhere there was a calculation on signal versus pressure. I want to reduce the fueling curve all together.

Your truck has to see boost to add fuel. Putting a resistor in might cause the truck to only see 10psi of boost so it's gonna add fuel for 10psi but that's it. And trust me, there ain't a lot of power to be had at 10psi. Not to mention that even if the truck is only seeing 10psi of fuel any box or programmer is gonna add even more fuel in than stock so your gonna have smoke then to. The only way to have a 100% smoke free truck is to go back to stock. Any programmer/fueling box you put on will have some smoke. It's just a fact of life. Some more than others but all of them will do it. Just increasing the timing will cause more smoke.

Juice with attitude - You can adjust low boost fueling. It wont eliminate the smoke but it will reduce it.

Got the 40hp DDP's Installed

They work great! Harldly any smoke at all, just when I romp on it. The truck is hella' responsive too, and the turbo spools up super quick. I am very happy with the 40hp injectors! My smoke problem is gone. I had no idea that the jump from 40hp to 75hp was that big of a deal, but thank goodness they (DDP) changed them out for me.
