When I first got my PS2 it was about a week before I got a memory card because they were sold out.
Anyways, I started a game with the 128hp Miata and, like any beginner, the only mods I did were horsepower mods, and I still found the car quite manageable.
But before I got my memory card, I had started about 5-6 games and then just had to turn off the Ps2, but a few times I tried the Trueno and one of the first mods I did was some stage of turbo, and me and a friend who had started that game found it very hard to control, it was oversteering like mad whereas the Miata had no such problems.
