ok for all u lot that kno your stuff bout scoobies and stuff:-

mods on car as follows
nur spec exhaust with revolution downpipe (de-cat)
greddy profec type s wlwctronic boost controller
255l walbro fuel pump
uprated fuel regulator
afr
induction filter
z4 ecu

now quiery is
since getting the fuel pump/regulator/afr/greddy EBC i cant get the boost anywhere near 1bar

when i had all stock parts on i could boost at 0.9bar

ill b honest the book is dble dutch on setting the EBC so mayb im doing it wrong

so if any1 can shed a light on this problem or mayb offer a hand too set up the EBC correctly (not fitment) just the boost settings id b most grateful

 

maybe all the parts you are adding are altering your boost,the greddy ebc cant be setup right either !!! maybe a trip to a proper tuner and a few £££ spent would make a huge difference

 

I had problems with my greedy profec B ebc when i first fitted it,the reason being i had the cars standard boost sol still plumbed in. I disconnected all the pipework to it,leaving the electrical connector on,and used the greedy one as a direct replacement,now it works fine.

was fitted by the supplier m8y

i think it has been, but ill dble check cheers m8

any1 else with some helpfull advice pls

 

stick a dawse device on, see if it will boost past 1bar to eliminate the turbo

1bar is not that high , sounds like the pipework might be on wrong IMO
