Here you go:
Red - stock
Blue - Powerchip software, filters, Underdrive Pulleys, heat spacers and IAT relocation kit
Green - blue plus headers and fine tuning.

I Drive AMG
Your graph is only showing a 16hp gain with Powerchip software, filters, Underdrive Pulleys, heat spacers and IAT relocation kit?
I thought I saw a graph of the powerchip software upgrade giving 23hp alone?
Seem's like a lot of work for not a lot of gain

You are looking at peak numbers, look at the area under the curve. There are consistant 20-30RWTQ gains in the low and mid rangse where the car is driven every day.
The next bottle neck on the 63s are the air boxes, now that the headers let exhaust breathe, our CF air boxes will push the car closer to 460sRWHP. That is close to 50RWHP/40RWTQ gain on normally aspirated engine with a very mild cam timing.

E55 then E63, now back to an E55
Performance aside, how do these SOUND on 63 motor?
Compare it to resonator/sec cat delete?
i.e. Just shorty headers nothing else --- compared to no headers but res/cat delete?
Thanks!

I think the blue curve represents VR530, which doesn't include software 
But honestly, 50 rwhp with minor bolt-ons is a great gain from a naturally aspirated engine Vadim.....
