well im running catless and i have a tune so i would guess that if the problem started after the cats were removed then you might wanna have it tuned or if it has a CEL or the service engine soon light on, get the SCT and it has a code reader that should tell you the problem

my car gives me a CEL for "catalyst efficientcy below thresh hold" or something like that so i just use my SCT when ever it comes up and clear the DTC
