I recently installed an Edge Evolution CTS and an aFe intake on my '06 megacab. The intake is huge, much bigger than I expected but from my knowledge, more air for a diesel is better. Other than these two applications, the truck is bone stock. I was reading through the CTS user manual and read that the programmer and addition of a CAI could cause "excessively lean conditions which could cause pre-ignition leading to detonation. " Since I'm running the stock fuel pump, could I be harming my engine with the two parts combined? I've only ran the Edge on the economy tune since all I'm really going for is fuel mileage. I don't expect to ever add more than what I have other than an exhaust.

No, you'll be fine.

Diesels can run pretty much infinitely lean without an issue. unlike a typical gasser where fuel is introduced with the intake air charge through the valves, your truck is direct injection (some newer gas motors are this way). The timing in a direct injection diesel is controlled by when fuel is injected so there is little to no chance that you would ever see early detonation from the addition of a CAI. Nitrous is about the only thing that can lead to an overly lean condition and early detonation.

Thank you both. That was the solid input to put my mind at ease phale. I appreciate it.

Get rid of the edge and go EFI live you'll see a world of difference and be 10x happier. Truck will run better as well

Most diesels have no throttle as we know it in a gasoline car. Mostly (but not all diesels always) they have open air intakes and take a full load of air in each cylinder and adjust power by amount of fuel only.
