50-75mph in 3rd gear: 2.08 s. 2.55 s.
50-75mph in 4th gear: 2.98 s. 3.63 s.
50-75mph in 5th gear: 5.23 s. 7.31 s.
0-60 mph: 3.68 s. 4.35 s.
0-100 mph: 9.28 s. 10.49 s.
1/4 mile: 11.89 @ 116mph >>12.75 @ 111 mph

Enough said
g-techs are hardly accurate enough to rely on at different locations. i only use one to see what my mods do to my times and i use the same strip of road every time.

besides that, i never said turbo cars aren't affected by elevation, they just aren't affected nearly as bad as N/A or S/C cars are. turbo cars have to worry about the turbo(s) taking longer to produce the same boost at elevation that they would at sea level and heat produced by the extra work the turbos are doing
