just wondering i think im wrong. you all know in nfsu2 (game of ricer fantasy)when you do the dyno runs you can fix up your gearing ratios to your likings and then do the dyno again and it changes in the charts. does this happen in gt4?. i havnt really tried tuning much except when needed but does the torque curves thingy change in gt4 after you customise? i havnt noticed it change.
