just wondering if anyone could shed some light on a friends focus st, he has a milltek stainless exhaust and sport cats, has an uprated intercooler but unsure of make... it has graham goode filter mod, and has a bluefin stage 3, lately it peaks near the red and drops back to 3/4 of the way on boost gauge, at around 5000 revs it drops off more to half way and doesnt pull that well, we plugged in a scan gauge today and noticed the charge air was reaching 29-30c, ambient was 14c and damp, is this normal??? any help or ideas would be appreciated.
