'' I have a problem with my car on idle, I have an EVO8 – full race engine – a month ago I removed the Air-con compressor, removed the pulleys and shortened the belt , the car was fine at first, but then 2 hours later the rpm is down to 200 then 100rpm the engine dies... and by the way, my cars is running on F-CON, is it anything to do with the tuning or is there something wrong with the car? ''

i would say start simple theres not much that can cause to just die out....start testin fuel pump, cam sensor, crank sensor...any cel codes??? could be tuning related if its not tuned right at all...???? post up more info about ur situation theres gotta be somethin simple, check for boost leak first.
