So, on the subject of the car in DSPORT...
The baseline pull was abnormally high for a 370Z.
We can, however, normalize the results, which make for some very believable findings... It isn't exactly scientific, but it's better than nothing.
If we go with the "275hp stock" number that most people agree is the average...
275 / 293 = .939
409 * .939 = 384HP Stillen Baseline
All the other ****:
453 * .939 = 425HP.
Which is believable in ideal conditions.
