Hey guys, I'm contemplating gutting the cats on my 2003 1500HD due to the truck having many miles of severe misfires under the previous owner. I was wondering if anyone could provide airflow data for a healthy LQ4 that I can monitor under WOT with my scan tool so I can have a before and after comparison to see if opening up the cats provided any actual increase in breathing.
Appreciate your input.
