re; mk5 2.5 turbo
ok youve done away with the epic setup and replaced it with a bosch mechanical pump.
from information gleaned from forum you adjust the rear screw on the pump by 1 1/2 turns or until it smokes to much.
this much i understand and it seems to work
but , in other threads about upping power on non turbo versions you are directed to adjust a different screw on the pump , one on the top which apparently does the mid range fuelling.
please could somebody advise on what exactly both do and what is the best procedure to extract maximium power on epic to bosch 145/146 conversions without unintentionaly f*** it up.
cheers Russ
