Does anyone here even run the diablo tunes? They don't enjoy a good reputation, I think in particular due to the tuners ...

Intake adds little to no value other than bling unless you do the full system: intake, downpipes, exhaust. A dropin K&N filter easily nets you the most gains.

As for engine differences, there are a few minor differences in sensors and clearances in the engine bay. Beyond that, one of our members with insider knowledge can better answer that question. The biggest control difference is the programming of the PCM - changed a lot in 2013.
