Hi Guys wondering if u can help me here. I`ve just converted my pride an joy ford fiesta xr2 to an RS Turbo. I was previously running an XR2i engine an loom in it, and have now put in a Fiesta RS Turbo engine, gearbox, cossie map sensor, ECU , exetra.... but not the loom but have done pin change an map sensor. I have piped and wired it up, and turned it over, she seems to be idleing ok but then cut out. Started it again an took it around the block seems to be boosting fine but lots of black sooty smoke pouring out the exhaust. I have been told this could be over fueling??? I know were the pressure regulator is on the alan key do u turn it left or right to de-crease the fuel pressure if it is so?????? cheers dean
