Impreza UK running lean of dyno.
 

Hi all,

I have nothing but problems since I brought my car UK 2000 v6. I brought the car, it's got td05, decatted, 3 port boost solenoid, fuelab fpr, ramair filter and rcm fuel pump.
I took the car to get it remapped but the car was leaning out at 4000ish rpm. Didn't seem like any vac leak's, maf works, plugs are new, coil pack is new.

When I'm driving the car if I have half throttle I can get through the whole rev range, when on any more than that the car bangs then I back off.

any ideas would be great. Thanks.
