Default Cobb Stage 2.5 VF34 map + CAI + Protune = gains?

I know that STIs are seeing HP gains with CAI's (APS, K&N Typhoon) with stage 2 Protunes...but on the 2.0 are there gains to be had with adding a CAI to a VF34/pinks/pump Protune?

I haven't seen any plots or heard tuners talk about this since the focus has been on the STI...has anyone?

Yes, a Protune is a good investment. When I was using an Injen CAI, I experienced a significant increase in drivability and saw gains throughout the powerband going from the off-the-shelf "2.5" to a custom Protune.

I'd say if you're running the OTS map, and are getting protuned, it's a good idea. Not sure if getting protuned again with just the addition of the CAI would be worth it, but I could be wrong. A local guy here got 19whp from a CAI on his STI.
