I'm curious here, as the only experience I have with larger injectors are the ones I'm running. 40% over tips i swapped onto my stock injectors, with good balance rates.

My truck seems to smoke more than my liking sometimes. specifically this morning, truck is cold, I'm traveling so I cant plug the block heater in. I start it up, let it warm up to over 100 degree engine temp, start driving slow, not beating on it. Driving down the road in stop and go up to like 40 mph, it seems like if i give it more than 5% throttle i see a haze coming out the tailpipe (can see it in the headlights behind me) and if i even step on it to say 20% throttle, you can see this haze fill my lane up. Not blacking it out but just like a fog behind me.

Once its daylight you really cant even see it, mainly in the dark. Seems to dimish when the truck is up to operating temp. Is this normal for big injectors? I have noticed that since my injectors, after driving for awhile, say 300-500 miles, if i wash the truck, there is a slight soot buildup all over the rear of my dually fender above the exhaust

mine doesnt smoke unless you get on it some, then it dumps. normal driving there is almost never a haze. but you have dual pumps and turbo my stocker vvt probably helps cut it back

I have twin pumps and 68mm cheetah. And yes idle the smell of diesel is stronger, but every truck I have ever been around that had big injectors smelled stronger. Also did you guys notice the injectors being louder than the stock ones?

100% injectors no haze at idle and clean burning ~500hp street tune. It's all in the tuning.

You will be good to go then!

The one thing I have learned with my 100% and doing my own tuning is it takes some fine tuning to get them happy for DD.
