CFFB CR motor tuning

Has anyone been tuning the CFFB motor with good results? If so what sort of mods have been applied.

We did a few 250 and 300hp cars.
Italians also have some strong running golf 6, with same HW.
Injectors, cp3 upgrade, rail sensor, turbo-IC-DP.
There are some videos published on my page in the signature with 100-200 runs.
