Ok so here is the problem , the car runs perfect when cold .. after like 15-20 mins of running , sometimes more .. it starts idling higher and bogs at low rpm ,

what could be the issue? it idles great sometimes , and sometimes it idles high , whick makes it Bogg.

 

clean your IACV, and bleed the coolant super good.
turbo....are you using crome? adjust your IACV activity

 

-Has this always happened?
-Is the car tuned?
-If so, what is it tuned on?
-Does this bogging occur only once the car is warmed up to operating temp? (time doesn't really tell us much)

 

The turbo was installed a phew weeks ago , and was not doing it the first day ..
it is running an FMU
if i ride the car without hitting any boost , it will never bogg ..

if the car is warm and i boost , then after that the idle becomes higher and it bogs unless i floor it .. flooring it is not a good idea since it burns rubber lol

 

The problem rests on your FMU. That is by far the worst method of "tuning" available for our cars. You should look into getting something like Crome. It is cheap by comparison, but will allow you to not only make more power than you are currently, but you will have a lot better drivability as well.

What i think is happening is that your FMU is adding too much fuel on boost which afterward is causing it to bog. You have to boost again to lean it out which rids the engine of the excess fuel. You could also have a clogged return line which is keeping rail pressure up once the FMU increases it...
