2011 9C3 Owner

Hey guys, I've been sitting on this Caprice for almost 8 years now and haven't done much to it or driven it but I've kind of been thinking giving it some love and doing some mods before I swap it for something else. It's a 2011 that I bought brand new in 2011. It's a 9C3 Detective model with the full center console and carpet/upholstery. It's only got 45k on the ticker and has always been garage kept. A local Chevy dealer who I've bought other cars and trucks from sold it to me when they first came out. I thought it was very interesting and the SS hadn't come out yet so I picked it up. Since then it's been just a weekend cruiser here and there.
I had a local shop do a tune and intake, they also swapped on the 20" Camaro wheels. They dyno'd it to a lousy 310 WHP. I doubt they tuned it and the Ram air intake sounds great, cleaned up the engine bay, but didn't do too much performance wise. They also did low profile electronic cutouts from DMH that leaked since Day 1. I see they have the old paper gaskets so I may try to swap them out for RTV but I'll likely just do an exhaust instead.
So I guess I'm really wanting to do the DOD delete and a cam to try and get some power out of this car because it just hasn't been the ball of fire I was expecting. A couple questions though:
Can I do the cam and DOD delete with the motor in the car? I don't mind pulling the front clip and radiator just wasn't sure if this was a giant PITA or if it wasn't too bad.
With a mild cam and DOD delete can I get anywhere near 400 WHP? I'm not wanting to mod the trans or converter at all, just looking for a reliable daily driver that pushes more horse than 310 at the wheels.
Also, for the White performance radio unlock do I need the BCM reprogrammed by a dealer or is it as simple as popping the silver box out and re-installing it?
And last but not least here's a pic of my beast:
