Ali,
Its not actually a higher octane, its merely a different octane reading MON vs RON. Overseas "98" octane equals USA "93" octane, you still have to move up 7 octane numbers to achieve true 100 octane (so I guess for you it would be 105 octane).
E55amgfan,
22% is the correction factor for Front engine, RWD auto on the dyno dynamics dynos and from testing its usually within 5HP of actual crank numbers using that correction factor on bone stock AMG cars.

Thanks I overlooked that it was a dyno dynamics which means more loss over compared to a dynojet where you can use 18% or so to calculate crank numbers vs. 22% for the lower reading DD.

its nice to see better numbers from our cars. There is hope to keep up with the supercharged and turbo charged cars of today and future.
Pretty soon.. you will seeing boosted 4.4v8 from BMW and I'm sure they will be able to hit 500 RWHP with just a chip and exhaust mods. I just hope they stick with the 6sp auto, cuz if they add the DCT or 8sp auto from the 7 series.. man those things will be nice.
Or those nice CTS-V pushing 550 RWHP with simple bolts on and tune
Yo can call this one 600RWHP due to the dyno machine used.

Was just curious... no biggie.
Read an interesting thread about a 240 that made boatloads more hp/tq on a DD than it did on a DJ, because the DD had an inaccurate barometric pressure reading.
From what I gather, "shootout mode" locks out all possible tweaks/correction factors, so the results just are whatever they are. DD's are great for tuning, but their shortcoming was trying to compare their results from day to day, machine to machine - "shootout" is DD's answer to address that.
Congrats again - look forward to seeing what it'll do at the track!
