Sharif - I am posting my dyno sheet below because I have it readily available -- I understand you want his and not mine though.
I was able to achieve 614rwhp on JB4 set at +4. When we turned the JB4 all the way down to 0 it put down 527rwhp. Every dyno reads a bit differently so it's better to go with the gain between stock and tuned vs. the final rwhp number.
I think your ECTG is right up there with everything else on the market right now. I have feeling I already said this earlier in the thread so not sure why I am posting it again lol.
I am going to add a Methanol Kit to my M6 to see what else I can squeeze out of this bad boy. I am working with M6Beast on it right now. I will get the car back on the dyno once we get everything finalized and post results.
Here is the JB4 dyno sheet:
