Hey guys, I have a 07.5 6.7 deleted.

I've installed industrial injection R2 injectors and an 85% over cp3. Truck has a lift pump, head studs, 5" exhaust, and a really nice trans tune. I have also milled off the stock intake manifold and installed a b&b tooling intake manifold. Stock everything else.

The biggest concern is that I'm sick of it smoking at idle. I've tried a lot of things: rail pressure, injection amount, duration. I'm getting no where.

Ive talked with tuners, they think it's just not getting enough airflow. There's no way, to me that's the problem with idle. If anyone can point me in any kind of direction, that would be great.


Thanks,
Matt
