Chipping Passat

I am thinking of chipping/remapping my 2003 Passat 1.9 Tdi Sport (130bhp). Ive read up on this quite a bit here and else where. www.angeltuning.co.uk seems to be a good bet for a decent remap. Has anyone got any experience of a remapped 130bhp passat and what sort of performance did you get ie. bhp figures or noticeable acceleration etc. Did it affect economy much, I do a lot of motorway miles so the engine on the whole is not driven hard just what the extra oommph when required. Any comments appreciated.
