Hey guys,
just want to throw some ideas around about the sever issues my friends car is now suffering after having a pcf installed and tuned at a fairly respectible brisbane workshop.
upon picking the car up my mate was told that they could not tune it to 11 psi as promised (std 33 turbo) as the actuator was screwed.. Now it was boosting up fine before taking it to the workshop - 8-9 psi arround 3k rpm as expected via a turbotech.
he drives it home and says car is running shit and lacking in power. Dyno sheets show 189 rwkw and good air fuel ratio. Now there is no torque graph, which i thought was strange? hiding something maybe.
anyhow full boost is not not made till arround 4-4500k rpm.. and it has been tuned to only run about 7 psi tops..
also car has all supporting mods, brand new fuel pump, fmic, pod full 3 inch zost with hiflow cat and now the pfc.
so i take it for a drive. strange rattle noise round the exhaust\turbo area.. lacking power for sure, boost does not hit hard. now we get home and let it idle. i can hear a rattley noise from arround the turbo exhaust housing when giving her a little rev. exhaust note sounds shit now aswell and not tough.. not to mention at idle she is blowing loads of black smoke and smeels badly like fuel.. and does not have a nice smooth idle. very up and down and just sounds wrong..
so from the above anyone got any clues as to what might be the problem. I am thinking possible exhaust wheel damage on turbo, hence rattles around the exhuast housing of the turbo..
Now if this is the case, would u not think a professional workshop would have known this and offered some advice more then just "mate your actuator is stuffed so it is not boosting properally" in which casue u would think they would replace it at a fee instead of trying to sell u a 3 grand turbo.
any ideas fellas
