The VW 1.9 TDi lump was originally 90bhp, they upgraded to 150bhp PD TDi in the Bora & Golf GT TDi, and then the tuners were able to take this up to 180bhp, so it is hard to say. I would have thought up to 130bhp with just a remap, then possibly another 10-20bhp with more mods, but that would cost ££££ |
