So I installed a Edelbrock E-Force Supercharger on my 2014, Z51 and after a tune, I was putting down 537 hp @ the rear wheels. How much crank or fly wheel hp am I making? Also, don't auto manufactures use the crank or fly wheel hp numbers when advertising their vehicle's hp? Thanks for your time!

Yeah, they use Break Horsepower (BHP) measured from the crank output shaft.
You are 630'ish give or take BHP with that RWHP. Not sure if you have an Auto or Manual which moves the numbers around a little depending...

Thank you Sir for your insight. It's a manual btw.
