Mk5 General Area / Re: K04 Conversion - Do you ever regret it? How is it for daily driving?

I'll use https://www.omnicalculator.com/conversion/torque-to-horsepower for a conversion to metric hp.
I took the values from the first log at 5760RPM and 274Nm, as I think they're the most reliable from your log:
Horsepower can also be estimated by multiplying the MAF g/s reading by 1.25, as the engine aims to burn 1.25g of fuel for every 1.0g of air taken in, creating 1 horsepower.
So at that same RPM point it's using 172g of air, 172*1.25 = 215hp. So your real hp number (I estimate) is somewhere around 215-225hp.
Your boost is definitely too low, that the first thing to investigate. Are there any engine error codes? But if you've smoke tested and replaced the DV there's only thing left it could be.
If your planning on going K04 instead of just replacing or repairing your K03, remember you need to think about the additional costs. A K04 upgrade needs S3 injectors, HPFP upgrade (I think) and S3 intercooler. As well as supporting mods like DV relocation kit and tune.
