Having purchased my car with the thought it was a standard 500 135bhp t-jet with a few nice options such as 695 tribute wheels, brembo breaks, koni suspension etc, I am now thinking my car could have the 695 brembo koni package. If this was the case it could have the essesse upgrade to 160bhp, is there anyway I can find this out without having to put it on a dyno. And how could this effect my insurance?

Pictures to show spec, any advice and help will be greatly appreciated
