in a nutshell YES.
just been remapped by p-torque, before map my pd130 was 145bhp running stock. after a pd160 intake and remap was 182bhp MAX (running a new standard paper air filter&sainsburies basics deisel) . its really transformed the car between 3&4300 rpm, im still getting 55mpg when taking it easy - 65-70mph etc.
i'm getting a pipercross filter this week, which should improve things a little more too.
im very pleased that i eventually decided on my p-torque remap as id spent along time thinking about it. This is also the first car ive modded in any way, without this forum i probably wouldnt have bothered.
