ive a problem with my wrx 97 jumping then making a big bang as it back fires ive been told to clean out the standard boost controller which i did but it still did it and now ive realised it only starts doing it when it warms up
any help would be great
 
Sounds like the timing is out and it is running rich. Has it been cammed/remapped? You really need to get this on a computer and see what the engine is doing when it happens.

One thing to check is the teeth on the cam pulleys/belt are properly lined up - one tooth out can cause problems and stop you hitting the power.
