If Gran Turismo wants tuning races, they need to kill the glitches. My best rounds were from tuning races because I exploited stupid things like flipped gearboxes, extreme rake, 1 degree of toe in, ass backwards camber, and shock settings that made no sense. If MCA had my tune he wouldve been top 3. How he made due with the tune he had I have no idea. Alien.
I race autocross in real life. If I set up my car like I did for Willow it would absolutely suck. Same for Miyabi. Yet I qualify right behind a world finalist because I am, if nothing else, obsessive. I didnt belong anywhere near him. Which is why I hate tuning. It's like an addiction, cant stop once I start. Then I hate the game because I keep picking at my tune and dont work on racing and friendships and having FUN. It's why I race street class in Autocross. I hand built my Jeep suspension, it's amazing, but it consumed a year of my life.
So, if GTS wants to include tuning they need clean up the ridiculousness to where if you nail it, you may find half a second on a 1 minute 20 second course, not 3 seconds on a 1 minute course in the GT 2, 3 and 4 cars. Or, I can pay 2.99 for a setup (hire an engineer) and it guarantees a competitive race tune. 3 bucks is worth my sanity (you dont get to see the adjustments, it's just applied in the background and tuned for the track). Make it 0.99 cents, whatever.
In my very humble opinion.
