So i did my DIY DPF delete about a week ago, and everything has been running great. I did the pressure fooler with the 110 390 set-up, and also put 330s in all 3 EGT probes plugs. Now normally my Pyro temp runs about 800 all day, but lately i have noticed it jumping up to about 1050. I drive the same way as when its hitting 800 but for some reason its running hotter now. I noticed that when its running hotter like this i hear the whistle coming from my exhaust, and also have a much deeper sound coming from the exhaust. Has anyone had this happen or might know whats causing this? I really have not had and codes except the P2000, and P2453 codes just once. I cleared those and nothing has popped back up. I was thinking that its going into regen but i have no programmer to really check if its doing that. No white smoke coming from the exhaust like i have read that some people have. Any ideas?
