Every engine is a tuned engine then. This engine is bespoke and purpose built, and mass produced. Find me a tuner that does that.

What's more interesting is that the 'vette with its huge 640hp engine for <1500kg of weight, i.e. 425 hp/tonne, did only a bit better than the GTR with measly 275 hp/tonne, and worse than the tuned GTR (V-Spec) with 345 hp/tonne.

What is more interesting is that the ZR1 could easily go faster, but they didn't put the absolute Ring master's in the car, nor tune the suspension for the absolute NS lap... but rather for people who drive their cars. Looking at the video, there are often 1000 rpm left in a gear+ when the driver is shifting... allowing even more time to be "made up" for going all out.
What is more interesting is that the ZR1 is a drivers car, where the driver is responsible for what the car does, not a series of processors with 10,000's of lines of code to allow the car or disallow the car to do what the driver want's the car to do.
What is even more interesting is that it isn't a ringer. Power claimed is power made, was done in higher levels of heat then what Nissan did, wasn't using racing fuel, wasn't using hand-cut slicks, or semi-slicks even... or different engine tune to stock.

And engine power is just a question of tuning, you can have as much as you want; even the small engines of the old Skylines have been tuned to over 1000hp.

Is that why Top Fuel cars are all high displacement supercharged OHV engines, and none are boosted straight 6's, 4's, 10's, 12's ......?
Boosting + higher displacement yields more reliable power
How many 4 and 6 cylinders have you heard about being rebuilt when running over 20 psi ?? A much smaller number of high displacement engines
Tuning you describe is solely what are known as "dyno queens"
Well done GM, well done.
