lately my car has been giving me some hesitations...

it would start when im cruisin on 5th gear around 3K RPM... the car would just BOG and start hesitating on low rpm... when i go to complete stop, the idle would be fine but its lags getting the car to run.
*note* idle is fine but when i rev the engine it sounds like its choking....**

i gotta revved it around 2-3k for car to run smoothly, once i get it on other gears, it drives fine...

am i running too rich??? is my FMU giving up on me??? please let me know what you expert thinks...

*note* the vacuum reads normal and turbo don't have a problem spooling...

here's my set-up

00ex with apex world sport exhaust
greddy turbo kit
FMU
missing link
blitz BOV

also after turning the engine off and letting the car rest for a lil bit, the car would run normal.
