Hello mate, just to let you know you've posted in the wrong area, should have been in turbo tech or similar anyway, what exhaust system you got? Your getting boost creep by the sounds of it. Best thing for you would be either a decent boost controller i.e Blitz DSBC, an uprated actuator would be a good idea aswell. Failing that you could port your wastegate. You must have a very free flowing exhaust system to be experiencing fuel cut with what your running i.e cat and standard air box! Or your actuator may be uber fooked!! Hope this helps. Oh yeah and definatily get a boost guage if your gonna be playing with the boost!
