Livernois gives you over 100 awhp, it is worth borrowing a PC for. On your first go request all the tunes you need, they load into the hand held tuner and you can go back to your Mac.
Ex: 87, 93, 100, ms109, tow. You pick 4 plus stock tune.
Not much in terms of go fast bits, drop in panel filter, thermostat for consistency. Rear engine mount to help with wheel hop. Stock Pirellis are trash, summer tires change it into a different handling vehicle.
