Ibiza sport 130 bhp tdi remap cost?

[minimat]

Hi I've currently got a ibiza sport tdi 03 reg that im wanting to have remapped. The current spec is 2.5 inch front pipe back exhaust with decat, green cotton panel filter and all freshly serviced. I'm also looking at getting a 2.5 inch downpipe asap.
With these mods what sort of power am I likely to expect and what will be the cost involved? Also is your stage 1 map generic or a custom one?
Thanks mat

Hi Mat

With the mods you have there i'd expect about 180hp or so, all the mapping is custom on the rolling road. £345+VAT for this one.
