E92 325D 204 bhp Tuning Chip

[tarks63]

Has anyone got any experience of chipping the BMW diesels?
I have been looking on Ebay and Pro-Bitz seem to be selling alot around £100 as a plug in and play and have excellent feedback.
I know people will say do a re-map but thats around £350 and what I am looking for is a quick plug in and go item that should increase the performance to that of the 330D as it is in all essence the same engine.
Any other reliable cheap tuning chips that people have used and recommend would be helpful.
Thanks

PSI Motorsport if they are still selling in this country are about as good as it gets tuning box wise. I don't know if I would trust something mega cheap under the bonnet of my own car.
