What engine is it from? Mk3 8v, 16v? Mk4? I would say that unless it has a turbo, it isnt really worth getting it remapped if it is otherwise standard. Look more at other areas such as aftermarket exhaust, an off the shelf chip (can be had from ebay) and probably more effective - airbox mods
With a little fettling on my mk3 16v gti, I got 172hp and 144lbs of torque at a recent rolling road. When you consider that standard is supposed to be around 150hp, it's not bad for not alot of outlay (especially when you consider a custom remap is circa £400 and on a naturally aspirated car you probably wouldnt even see that just from the remap) Modding airbox, performance filter, cold air feed down to the bottom of the bumper or grill, exhaust, cheap chip would cost you less than that and be more effective.
