Vehicle Performance Improvement Calculator?
 

Good news for vehicle owner. How will you know performance of your vehicle? Do you wanna know performance improvement of your vehicle? I calculate my vehicle performance by the calculator is http://www.smartremaps.co.uk/performance.html

how is that accurate? how does it goes or how does it compute the performance of the vehicle?

Just checked their site... fun but they could be more accurate if you can also submit installed mods on the car... then still it also depends how you push your pedal ;)

thanks for the input I'll try to use that tool whenever I need it.

probably kyled the one we usually use, not sure how to call it can't remember it actually :)
