I think a much bigger turbo and air intake will be required as well to get the job done.
Imo, way too many components to change and big $ to make the car go 1 second faster (0-60mph) and 1-2 second better on a 1/4mile.
The alternative is bypass the regalur 550 and straight to the M5 right from the start, at least you are half way there already and with just an ECU tune, you should get your 650hp.
