By the looks of things, the mods hes done should give him some decent results. What boost presure are you running?
Theres a guy ive got on my facebook (search Multijet tuning) who uprated his turbo and he had to get bigger injectors, Yeah he is running a 1.3mjet 75 but I should think there would be some limit to how much the standards could displace?
Pics under the bonnet?
I didnt think exhausts made a huge load of difference on dervs either? correct me if im wrong

I'm running 2 bar of boost. The benefits of exhaust upgrade are go down EGT and less backpressure.
