CLS400 Upgrade project

Hey CLS forum,
I own a 2015 cls400 4matic and am almost entirely happy with it. Coming from the R230 forum where I had an SL55 AMG, I lost that awesome power and torque that the SL offered. I probably should have chosen the cls550, but once again I jumped the gun before researching.
I'm considering going with a Weistec W.3 turbo upgrade package and tune.
The hp gains are huge and no engine internals need to be replaced or strengthened. I'd like to dyno before-after results if i move forward. Trying to locate a 4-wheel dyno is a problem, however. (its a 4Matic).
Potential 200 hp increases caught my eye.
Any experience or comments on my plan would help me a lot. Thanks everyone.

CLS400 4Matic EC Tuned
Just go with the stage 1 Eurocharged tune. It increases the horsepower by 150 and torque by about 180 pound feet.
