Default need help 07gt v8 cat converter removed

hi all

cat removed with mid x pipe and magnaflow catback

i am facing a slight problem after i removed my cat converter, the issue is every time i push the clutch while stopping or down shifting the RPM goes under 5 for 2 seconds then goes to idle and some time this cause turn the engine off, this also happening when i rev the car while stopping.

do i need to tune my car with SCT tuner? is the tuner gonna solve my issue?

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
