Right on as clifftrail stated.. The 416 HP is measured at the Engine..
Once you factor in the 16-20% drive train loss, you will get the number of Rwhp..
Which is the power being put down at the Rear Wheels.
Typical stock IS-F's put down approx 330 to 350 Rwhp SAE Corrected on a Dynojet
The OP's dyno graph showing the "367 Rwhp" number - with a Standard correction factor, is very Generous for stock numbers.

I'm new on this site and am almost a year with my 2010 ISF. I love the amount of info that I get here. My ISF is fast enough but I seem to get about 300rwhp on the dyno. Am I down on power our should I blame it on our weak fuel in South Africa?

Altitude is a bigger culprit than anything in South Africa. Where are you relative to sea level?

I've now noticed that they dyno'd the car in third gear. Also, I air filter hasn't been changed for a while. After the major service I replaced the filter with K&N, deleted rear cats and the car felt a lot stronger than before.
I even took on a c63amg and the guy couldn't keep up 1st 2nd 3rd. He only came closer as I was finishing 4th but in 5th I pulled another gap.
Could it be the filter and decat? I will dyno run again soon
