Stock vs APR Stg 1 using my performance calculator

Folks,

I entered GTI specifications in my performance calculator and got it to compare stock with APR Stg1. Feel free to play with the calculator. You can easily change torque, tire size, weight etc. and have it calculate different performance metrics for your specifications. You can also use it to compare with other cars (up to 3 others). It is complex but quite accurate.

Calculator itself is here: http://vlsicad.ucsd.edu/~sharma/Potpourri/perf_est.html
Information/help is here: http://vlsicad.ucsd.edu/~sharma/Potpourri/perf_est_intro.html

Anyway, on to the results.

Other performance metrics


Have fun. Feedback welcome.

I'm curious as to what you used for coefficient of drag and frontal area and where you got it from, if you don't mind sharing.
