looking for info on waking my 2013 Yukon 5.3 up. I’ve done the CAI and Magnaflow exhaust but she’s still sluggish and doesn’t wanna come out the hole. Thanks in advance

Common, likely due to the overly "safe" Torque Management programming. Make sure everything repair- and maintenance-wise is up to par then get a custom tune.

What is your intake setup? Is it an actual CAI?
