Pictures from Dyno on Tuesday

hi,

sorry to keep coming back to this but it's a major issue and hope that some of you can shed some light on this. i took my car to get it dyno'ed on Tuesday and surprise surprise it came out like crap. here are some specs on my car:

About my Car
Car: 2006 CLS55 AMG German Edition (bone stock, limiter removed by factory)
mileage: 26k km (18k miles)
No fault codes
checked air filters

About the Dyno
Dyno'ed on a dynojet (as in pic). The dyno has been tested and my friend's slk55 ran a 580rwhp and my sl55 had 435rwhp. so it wasn't the dyno's fault.

Funny thing is that my car has no problem keeping up with my cousin's m5 and my friend's cls63 on hard acceleration or on the highway.

my friend thinks it may be the belt slipping, is this common and if so would my chart look like this?

other mechanic suggests changing the i/c pump. wouldn't a code pop up if this were bad?

someone on the previous post had suggested checking for clogged exhaust. is this even possible and if so how would you check for this? I have the common "roaring" exhaust and it doesn't sound clogged.

btw, here's a video of my cls55 going 181mph a couple of months ago:

usully first thing that pops to mind is bad pump...but you are an 06 which means u should have the new pump.
Maybe fuel is bad?

did you have the car in dyno mode?

you should be at 390-400rwhp minimum i think

and no you will not get a sign or light if you pump is bad
