A secondary cat delete is a no-brainer as the ECU doesn't monitor them anyway...however there's limited power to be gained there. Catalytic converters aren't leaving much on the table anymore. I'd put this one in mainly a "I want to change the sound" category. Do you have the factory NPP?
The Roto-Fab CAI appears to retain the MAF scaling so that's OK. Some other airboxes look to skew the MAF scaling so they'd need a tune.
After that, things that change the VE like long-tube headers, camshaft, and cylinder head porting will need an ECU tune.
