180mm Pulley and Tune dyno results, what do these numbers mean??
Had a chance to throw her on the dyno today. There are multiple runs so its a bit confusing but to you guys who study these things its nothing.
The last time I saw the dyno I only had a tune and I put down good numbers, 411.68 HP and 421.95 TQ.
This time, I went with a 180mm pulley and tune and I'm not sure the numbers are as great as they can be. It looks like my peak was 416.21 HP and 450.22 TQ.
According to the graph I only gained 5 HP?? I understand that there's a huge jump in power (from old dyno to new) between 4K RPM and 5.25K RPM but it seems like all the power starts to drop off after 4.75K RPM.
What is that???
Are these numbers kosher??
The dyno guy (extremely knowledgeable) said it could be anything from an exhaust clog to the timing. WHAT SAYS YOU fellow AMG'ers?
Thanks guys!

it looks like your I/C pump might be bad. Its really hard to say just buy looking at the graph. If we could see what the AFR looks like, that could tell some of the tail. If this was my car I would be looking at the I/C pump to see if its working.

ASP pulley with Jerry tune.
Not sure about the technical stuff guys, but the IC pump is good. The tech checked it in between runs.
What kind of numbers should I be putting down with my set up? (180mm/jerry tune/eisenmann/res delete)
Dont get me wrong, the car is a beast and a half, I just thought I'd get better numbers on the dyno if that even means anything...?

Car is definitely down in hp/tq per the dyno graph you inserted. I bet it is battling heat somehow, what are you cooling mods, and what are the intake temps on the runs? I also wonder if he has belt slip or the incorrect belt size?

Thanks all who are responding, even the tech was baffled as to why I'm losing so much power.
What cooling would you recommend? Do you guys think there could be something warranty related that I can take care of for the price of lets say "on the house"
?

We did not tune the car, just ran it on the dyno to see what it puts down...

How did he check the pump if you do not know where it is?????? My car has 19000 miles and my factory pump was DEAD! They warrantied it with the new BOSCH MB replacemnt and the difference was absolutly amazing.

Yep, mine crapped out a few months ago. Dealership replaced it, but not sure with which one. I'll either replace it with my CM30 or keep the one they recently installed, depending on the part number. Going to be installing a HE anyway, so I might as well.
