1.4 hdi boost

[n33jby]

i have a 2004 1.4 hdi
decatted
bypassed EGR valve
abd a re boosted turbo (standard boost 1bar running now at 1.6bars)

what else can i do to make it more quick

 

[pgarner]

hybrid/ bigger turbo
bigger injectors
Remapped to take into account the changes

or buy something quicker / fit a bigger engine

 

[jarrus]

remap,

bigger injectors aren't really avaliable for this car, intercooler would also be a good idea.
