There is no guarentee that when you are out one day that the "special octane" fuel you will need is on sale where you might be - so again, of you paln on driving the car asa true street car on pump gas that can be driven anywhere, it should be tuned for and use common pump gas 
Otherwise - its a race car 
And to get back to the topic, an 800rwph boosted V8 produces HUGE amounts of heat - that has to go somewhere - on the street, you simply upshift and cruise for a few miles, car is cooler and you hit it again - thats not track driving, but can be insane fun on the streets - no argument there. |
Ok on a turbo car you play whit the boost levels.
Most turbocars run on the their full on a dyno when they drive it on track the run lower boost.
Their standalone ecu's on the market that have multiple maps.
Example you have map for normal pump fuel.
And you have a second map for racefuel.'
Example of such a ecu.

With this kind of ecu you have streetcar or racecar with one ecu.
