Are those from a inertial dyno or a brake dyno? You know that on a inertial dyno you can't measure the power loss, and that depends on a lot of factors, like the temperature of the tyres, the weight on them, the pressure, the transmission temperature etc...the WHP is accurate but it depends on these factors.

As F.I. says, if you haven't got the same conditions (where are the values, like temperature, pressure etc.?) the value themselves are not very reliable...

On their charts I see:
stock: 280 hp
exhaust: 310 Hp
Is that WHP? because our car was:
stock: 261.7 WHP
full exhaust: 284.3 WHP
So it's a 22.6 WHP increase.
BUT the conditions were different, plus the stock run had 69.3 hp of power loss, with the exhaust these became 71,7 (as the power loss is a % of the flywheel power, is normal to see an increase in it too)
So what's the flywheel HP on the F.I. car?

I see a few irregularities in the F.I. chart:
It starts at 2700 rpm. We've seen a valley in the torque curve at 2400 rpm but you can't see it in that chart.

I don't want to start a dyno war, just asking.

We went from 362 to 382.5 nm
