deco c

i was out for a drive last night and put the foot down.next of all the car seemed to go into safe mode or something as it would only boost to .6bar instead of the usual 1bar.its happened a couple of times before when i drove it reasonably hard(not redlining it) and all i had to do was turn it of and back on again and boost would be back to normal but its stayed like that now.the car is a 99 classic sti import with no mods at all.i was told it wouldnt be the ecu so im not sure.if anyone has an idea that would be much appreciated.thanks guys!!

as its an import it could be the fuel your using and the car is mapped to a higher rating of SUL.
