Car has started to be sluggish sometimes at low rpm's. I've read a bunch of posts but wanted to ask if any of these scan codes could be related. Any advice on where to start is appreciated. Car is deleted via tune. I was going to replace all vac lines regardless.

If you are tuned you should not see EGR related codes. What is that 483D?

The code I have is 4868. The egr is physically still there just tuned out. Ditto for dpf. I replaced all the vac lines but same problem. I followed a YouTube video on testing - first step was to disconnect a line off the turbo actuator the one at the back near firewall. When pressuring the left side of that it i can get the pressure up but then it falls slowly. Video says should hold. On the right side when hooked up I start the car and get no pressure.

So you indicate that car is deleted via a tune with DPF on place. How long ago? Everything functioned properly after a tune?

Im pretty sure tuning the DPF out and leaving it place is not supposed to be a thing. Tuning it out would stop regens, so it would just clog up with soot.

Yeah agree.

The car was tuned 3 years ago and it's been running fine since. For the past 2 years it hasn't been getting used much and rarely long highway runs which I know isn't good. It's a jr tune, and I was told at the time this would be fine, but may experience dpf problems down the road. Now that it's happening, and doing more reading, I certainly wish I'd never left them on but the goal at the time was to keep the sound/smell stock. I asked jr about the regen and haven't gotten an answer yet. Is it possible for it to regen still? What if I request a manual one through Carly. I've ordered some replacement parts so I'll update when those arrive and tune will be modified as well.

No once it's tuned out. Its tuned out. Your dpf is probably super clogged.
