Any one any advice on chipping a 110bhp Octavia elegance estate?

Namely are there any real benefits to it, and what chip would you recommend?

I`ve seen several types for sale but am not sure of whether mine is a PD engine or the other one!! and are the ones that just plug in the loom any good?

Any help appreciated.

The 110 is a non PD engine.... Dragon Performance tuning boxes seem to have a reasonable reputation, and many have a control on them so you an tweak the performance as u drive.

More power, and reputedly better economy if you don't make a habit of using the extra too much.
