Measuring bhp using android torque and obd adaptor

[rob77]

Hi guys

I bought a cheap bluetooth obd adaptor off of ebay and it arrived this morning. Have set it up and everything reads fine in torque but I'm a little confused on how I can see my cars max bhp. My car is rated at over 200bhp so do I need to be going at top speed and at a set amount of revs to see my max? Or does it need to be on a rolling road? I took it for a little spin and thrashed it a little but max I saw was 140ish.

Cheers

I thought the bhp would have come straight from the ecu or am I being dumb? 0-60 works perfect although I don't think I'm very good at setting off to be fair.
