First off new to this GM platform
Recently purchased a 2013 Cadillac ATS 2.0 LTG auto 6 speed. Previous owner did not maintain the vehicle to IMO proper standards. Previous owner had vehicle serviced at a mom and pop shop and should I say "Butchered" the vehicle with replacing parts NON OE and band aid solutions. Since ownership of vehicle i've replaced.....
MAF - GM OEM
VVT - Intake/Exhaust - GM OEM
MAP - GM OEM
BARO - GM OEM
Spark Plugs/Coils - GM OEM
VAC PMP/Hose's/All Valvecover seals/ evap valves on valve cover -GM OEM
O2's - GM OEM, Down stream Aftermaket "autozone" Walker
Cat/Exhaust - ZZP highflow/Exhaust complete
Catch Can system - ZZP
Spent numerous hours trying to get the car to just driver as factory for daily driver. My question is due to DP/Exhaust do I need to start tuning due to this or am I missing something. Datalog's what seems as if to many. Just curious to see if other LTG owner's have had the same issue's.
