Interesting how they calculate the WHP
It says you have 203 bhp which is you motor rating and its totally factory rating, so no change there, but then it says Wheel output > 156 hp 25% lost . Rear wheel rating should be 85% of the crack, so you car should actually have 175rwhp, which is again factory.
I'm just confused as to why they rated your wheel HP at 75% crank
