be more specific next time. each cars are different, as to weight, power, engine based, drivetrain, etc...you can't give each car the same tune and expect it to feel/drive the same.
edit: for the gears, if you want to get more top end speed, just expand the final gear ratio and tweak with the gears a little but if you want to other things, I suggest you leave it stock. let's say for example, you have a Civic CRX and you want the Civic Type R tranny gear ratios. look it up online and set it up from there other thing is that you'll have a 6th gear.
