Do you have a DI engine like all those cars?  They dont do anything too special, although their launch control strategy will include significant DBW throttle control as well as the normal ign & fuel cuts but mostly they are not popping and banging like a port injected engine because with DI you can use much more fuel cut without the normal wall wetting delays.

Hi,
You can use fuel pressure sensor from VW/Audi , this is the bosch sensor, cheap (50 usd) and very precise.
