Great news for you!...
I'd like this upgrade.

If you have the TCU upgrade in your vehicle, it may also have a modified red line.
Normally 6200rpm, but those that have gone to the trouble of a TCU tune have sometimes also gone for a higher redline to squeeze out some extra gg's. However this also involves a matched ECU (Engine Control Unit) tune as well.

You can test the red line setting by placing it into Summer mode, disengage the ESP (dash), put it in first and launch (throttle flat to the floor "WOT"). Best done with an OBD recorder connected to make sure your capture the peak rpm.

In addition, if you don't have a limited slip diff - you may tend to drift sideways as the wheels find traction and you'll leave one stripe on the road, however if you don't drift sideways and leave #11's then your even luckier 'cause you have an LSD to boot.

One of the downsides of the ECU tune...if you get that far...is that it may be tuned for some other mods that may or may not remain on the car. If there are any labels/stickers like "Eurocharged" on the TCU/engine bay etc then it would be wise to get in touch with them and provide your VIN to get some history of the tunes - if available.

Another note on the swap if you ever go down that route is - you'd best match your PN#'s for the TCU's as they are not all created (or coded) equal. I'd keep the TCU and enjoy W when convenient.
