I much prefer this conservative, comprehensive and realistic tuning approach to the approach of throwing stuff on the dyno, filling it with E85, cranking the boost and bragging about numbers.
Let's not forget that 280hp or so crank hp is what JDM icons such as Evos and GTRs were limited to not so long ago and those were anything but slow. This car is also light compared to most cars these days, not to mention the balance,
I think it'd be a heckuva fun ride as-is.
