first of all. you have fuel values of 6000 FV. that is not good. I would recommend starting with a new map. tuning the car below boost esp. column 10 and run the boost table setup fuel 120% over it.

no,no BM fuel regulator,so yes even with this amount of fuel was lean also the fuel pressure at idle is 4 bar and at wot 5 bar i didnt try the map cause i dont have the car right now living in a diferent country i will also try a new wb with the new rc's that i boughtGaskleppie wrote:Still lean? Do you have a B&M fuel regulator? I have seen at least 10 of them broken with these kinds of problems as a result.

Only thing i think of. Fuel pump maybe a Chinese Walbro? Or a broken FPR. I think fuel pressure is dropping at certain boost. e.g. Base fuel Pres+Amt(full throttle) Press+boost so 42 base pres psi with hose disconnect 40 pres psi with hose connected(idle) 42+7(psi boost) = 49 psi. Something most go wrong. Maybe run a line from gauge(inside car) to fuel filter to monitor FPR under boost.
