Hi, new to the site. 2017 ram eco diesel big horn. Just finished doing a delete for the def put a 4” lift on it with 35’s.

Took it for a drive and noticed throttle surge. Any solutions or pointers would be greatly appreciated. Thanks

You said you did a delete for the DEF, did you mean the DPF? What tune did you use?

Had my mechanic do it. Looks like a coolant pipe blew off when he did the mechanical delete.
