Ok today I installed my h&s mini maxx with od software and a egr block off with a cai. Threw like 5 codes due to the egr delete and still have dpf present... Now I have major issues. Shifting funny, revs up, stuck i'n first some times.... Programmer the truck back to stock and still happening? Is this due to egr delete and dpf still there ? I haves spoke with bobby at h&s and he thinks it is... This is a 2008 6.7 qc sb auto trans!!!!! Help!!!!!!
