From my point of view nearly 500hp is enough. It's hard enough using that around here short of track days. And we have"boy racer" laws where the cops can impound your car for doing a burnout. They call it sustained loss of traction.
Likewise for "unecessary display of speed".
So for any"christian motoring" you have to be very watchful for cops.
If I were to need more power, I'd throw a blower on, NA tuning generally costs too many dollars per hp.
And I had great results with a Sebring blower on an MX5 years ago.
