Tuning is really only beneficial if you're substantially changing the volume of air going into the engine, which requires remapping the fuel flow to avoid leaning out too far and breaking stuff.

On a NA engine, the best it can do is zero restriction on the vacuum the engine is pulling on the intake... And changing the pipes into and out of the engine can only do a couple of percent on that - at best - which is usually within the realm of the ECU to figure out on its own.

That and the VQ is fairly dialed in out of the box... There's just not a lot of hidden HP to find on such an established engine.

So, in generic terms, after buying the license for uprev and paying someone to remap the car you're looking at about a grand for about 10whp and 7tq.

By way of example, the NISMO VQ37 is technically full bolt-on and tuned and only generates an additional 18HP over stock.

You named off some good stuff, Test pipes,free flowing exhaust & cold air intake will gain you about 20whp before tuning & another 20whp after Tune.
Quaife makes the only Helical locking diff unit for your 3.357 gearing diff.
You have 4 very good gears to play with (0-125’ish)
A Sport or Nismo 3.69 gearing diff will help acceleration.
Unless you plan to run e85 fuel - no need for upgrading injectors or fuel system.
Look at Z1’s 400hp Package...it’s got things you have +1.75” primary headers.
Don’t expect to exceed over 330-340 after $$$$ of dollars spent.
But you can at least get down in the 12’s 1/4 mile..,very low 12’s possibly on good air.
