Hi , Im looking to add a little power to my A4 1.9tdi ( non PD ) 1999. looking to spend around £250-300. The company below quoted me £249 for a remap , but advised me that a Tunning box would best suit my engine being the Non PD ???? is this believable ? www.protuning.co.uk/ any advice would be appreciated , I live in the north west region ( near manchester) if any of you know of a remap company doing mapping at a good price.
