lol, downforce doesnt work without speed, lollers, so it cant help in accel that much if at all.
second, the perfect tune may differ from person to person, try to make ur own and post it, maybe we'll cehck it out.
to increase accel, make the forst 3 gears short or make it shorter, then leave 4 alone, then make 5th gear a little bit longer and u can just make 6th hella long, then ud have hella top speed and good accel
i dont have the escudo, but the awd and the 4wd cars are the fastest at accel, try those, maybe the escudo is either one of those, but yeah....
