09 c63 amg dyno number
If your car can put down the same figures on another dyno, i'd say it's as good as having a 500whp glory dyno

TBH it's still not an awful number. Wasn't CaptnCharisma at around 470whp, albeit on stock headers/cats...but then he was running the correct E85 tune for it. Maybe you need the aggressive E85 tune loaded to your ecu.

Look up the original E85/Flex Fuel thread from the autumn and you'll see what I mean.
You should ask eurocharged for the v7 regular tune. It makes another 10-20whp over v5. Probably put you at 500whp without tuning for e85 and then be married to it.
But if you plan on running e85 only then get the v7 e85 tune and pick up another 10-15whp
