Pretoria too ...... The car goes great when the temp drops a little.....

Yep - proves the point for water injection!

Yea.....How much though.. (instead of a turbo upgrade?)

Is it just my imagination or is my stock 1.9Tdi actually pulling slightly better with the colder weather???

Not your imagination, your intercooler works better, and therefore induction temps are lower, = better power. Air density/ saturation helps too.
You can have that all the time with Aquamist
