is it possible to turn my fuel pressure up my self to 3 bar as im running a ofab set up with a 195 chip beige injectors .. ive been told it needs to be turned up to 3 bar

 

It needs to be 3.5 bar, your options are fit a cossie fuel regulator or use the standard frst one, fit a fuel pressure guage and adjust it yourself.
I recently just did it with beiges/collin 195 chip and until the fuel pressure was 3.35/3.5 bar on boost it was very lean.
If you havn't got a afr guage or fuel pressure guage best bet might be to take it to a tuner and let them set it up to be safe.

 

i got car up and running today but cant drive it as fuel pressure needs setting can i do it myself with out a gauge just by counting turns . i cant take it tuner just yet as need to run it in for a few hundred miles
