I swapped on a new ported throttle body over the weekend to replace my nearly 6 year old ported unit from WeaponX. I sent a brand new OEM core to Soler Performance and had him machine it to spec. Long story short, its actually engineered with read R&D testing to back it up vs. just porting to make it smooth & pretty.
Plenty of actual data here:

We'll see how it feels once I fire the car up for spring, but figured for a net cost of $200 (after buying a new core and selling my WeaponX) it would scratch that mod itch a bit and give me a little wrenching time in the garage.
I doubt I do much else to the car this year besides the above post plus general maintenance/fluids and what not.
