TDI Chip Tuning: ALH 90 PS - Urgent!

Hello,

I'm new here and have a question about chip tuning for a 90 HP TDI Golf 4, manufactured in 02/2000, with engine code ALH.
Is it worth chipping this engine? Or does it significantly increase wear and tear on the machine?
My car now has 59,000 km (approximately 36,000 miles) on the odometer. It consumes very little oil, and I don't need to top it up within the 15,000 km (approximately 9,000 miles) oil change interval.

Has anyone installed a chip in this engine? How much power does it add? And what about repairs and durability?
To what extent does the final speed increase?

Bitte ein paar Erfahrungsberichte. Wäre echt super. Thank you.

Thank you for your reply, Best regards, Benny.
