Hi,am new to the forum,im currently on my second uk my98 classic impreza,does any one know what the standard boost pressure should be? also would the addition of a de-cat bear any difference on the boost pressure? my first impreza was boosting 1.2+ with de-cat,after market headers and up-pipe.The one i have now the only mod is a cat back and dv,and she is boosting 0.7 max.is this normal? cheers in advance

Johnny.
