So many of TJ's Mods only seem to make a TINY difference... I wonder exactly what each of his modifications DO exactly. Some are fairly obvious, such as tires, weight reduction and suspension, save for the amount of "help" they actually provide. With the NOS, do you simply get just a little more of it (lasts longer) or is it (also?) more powerful? Does the "Engine" upgrade affect just acceleration, or also the top speed and/or optimal shift point?
My main reason for asking is that I want to beat the game with a car optimally designed for DRAG races -- I *THINK* I want to use a transmission mod, but I don't want to sacrifice the top end in exchange for acceleration.
