Anyone know what the highest boost pressure i should be running safely for my focus RS as ive been told several different answers?

 

25psi would be the limit i emagine with the correct turbo. All depends what your engine has had done but you will struggle to break the engine on the standard turbo anyway

 

cheers mate, thats confirmed what i thought! Iam running full blueflame with decat, k&n gen 2, dreamscience and it peaks to 25 psi on the fastest setting although it only holds it for a second then drops to about 20-21 psi!
