OP the first mods on my 2012 V6 automatic were an Airraid CAI and Bama tune. The tune did make a noticeable difference in throttle response and top end power. The tune also firmed up the shifts quite a bit.
I ran the 91 race tune. The CAI made a slight difference in sound coming from the engine compartment on acceleration. I don't know how much it actually contributed to the gains.
All in all the tune/ CAI are a worthwhile addition. But just keep your expectations realistic. A tune and CAI, are not going to turn a V6 into a GT.
