True anti-lag (massive ignition retard and lots of fuel) will bugger most turbos fairly quickly, and generates massive amounts of heat for the turbo/exhaust manifold to dissipate, and give them both very short service lives.
Launch control- great, but you'll have to get front wheel speed and rear wheel speed as variables to control to, which isn't that easy on standard Polo components, but can be done.
When you read ECU specs and features, also consider the amount of time and effort to calibrate them properly yourself, or the cost of paying someone else to do it, not cheap.
