Nice car, i see from one of the pics you are running a fuel pressure regulator, in fact it looks like an rising rate FSE PowerBoost valve (i run something similar but made by SARD you can see it in my car thread), did you also uprate the fuel pump?
I can't tell frand I hope that if you are using a2nd injector for the turbo? If so it needs to be plumbed in series as ifs its not you will only get the pressure thats set from the throttle body top as the fuel will always go for the easiest route. Standard regulator is found on front of throttle body in front of injector, has a wax sealed 3mm Allen bolt in it, pic out wax and turn clockwise to increase pressure, I foun dthat you can get up to 1.8bar from it as once you get to about 2bar it locks out and has no more travel left.
So you need to go to 2nd injector first then the pressure regulator, then the return from that goes to throttle body for primary injector and then returned to tank.
Tho to look closer it looks like its only the single injector, does this provide enough fuel for your requiremnts as I worked out its at 100% duty cycle at about 85bhp on a N/A car?
Excellent work tho, even if i am asking lots of questions...
