You have to remove the DPF but the EGR the tune just deactivates it and you don’t have to do the DPF delete or egr if you want to you can just do the HP tuning
Yeah, for sure my email is thefscbusiness1@gmail.com and to fix your problem you need to get the tuner I am showing in this video the link for it is in the description
Yes, sir, it can be done with pretty much anything that has a DPF EGR or DEF system if they don’t have a tune file for your machine. They will make one for you.
