DD15 LOSS OF POWER. INJECTORS or BAD DPF DELETE???

[Brock]

Man I am with Unilevers! Never try and fix a sick truck with a tune!

If you swapped the tune and still no change, your engine is sick.

If you have no boost leaks, check your fuel pressure, also as stated by others you can check for exhaust restriction.

Do you have a boost guage and a pyro? What boost and what exhaust temps are you getting driving down the road or pulling hills?

Also, if your injectors were over fueling then your exhaust temps were probably so high that it cooked your turbo. Maybe the turbo isnt activating properly.

You need someone who knows what the Fu$# they are doing.

Case and point. I had a mechanic rebuild my engine, it ran like crap, mechanic messed with it for a week trying to figure it out, all the while I wasn't able to work..... he was about to tear the motor down again when I said FU$# this!!!

I went and saw Unilevers, drove it down there misfiring and all, within 15 minutes he found a couple plug were plugged into the wrong spot and I was off to the races..... proper mechanic skills with proper mechanic tools.
