I have tried the DTUK CRD3+ chip and although it gave loads more power and felt great having my head under the bonnet everyday messing with the settings and having numerous engine warning lights enough was enough and I removed it and sold it on. 

I have been left wondering if there was anything else that can be done without affecting warranty and I have come across some OBD plugin chip which.

Any thoughts or reviews would be great thank you.

THank you. As I guessed. Load of crap! 

A cross over from your other thread but I would seriously recommend getting your car looked at before adding any further devices, remaps or similar.  If there was a problem with the car then Skoda may require some diagnostics etc before signing off on a warranty claim.  If they dig deep enough they'll find something and use it as justification to not pay up.
