Hello everyone,

I've searched the forums for answers, but I am struggling to piece together my options.

I have a 55 plate 1.9tdi 4x4 estate Octy.

Over the moon with the build quality, the reliability, the spec., etc, etc.

16,000 miles in 6 months & no drama at all. It is screwed together better than my dad's new 4x4 Jag. X type estate that cost considerably more !!!

But I do think it lacks a bit of go.

What can I do to up the HP & torque?

Can I do this in a way that can be removed for warranty/service etc.?

I've seen devices for as low as a few

Possibly just a standard remap (non chip type). The sort of one that can be 'undone' if required.

Unsure of the technical details however. (have no experience of it myself I just looked into it when I had an A2)
