you say this but a flex tune will come in handy one day when you need it most.
great turbo, bolt on, hidden and looks factory but will make the power to match. Less hassle from straying eyes etc etc, This will also make an excellent streetable setup as well but again this all comes down to what you want from the car.
you always want wiggle room. If you want a 1000whp buy parts that support 1500whp or more, this applies to everything. 1. because you may want more power and its easily achievable. 2. less likely to have issues with stuff breaking when they are on the edge of the said limit. I can keep going here but I think you will get the jist
lol im surprised you questioned that.
