just wonder if anyone could have a stab in the dark my car is a 2002 wrx has full decatted exhaust jr panel filter dump valve walbro pump and regulator ,ecutek remapped most of the work was done bhp developments knocklink system and runs 18 psi boost on a cool day 16/17 any other cheer Lee
Oh also clutch is starting to slip do ya need to change flywheel when changing clutch.

 

i would get the flywheel skimmed at least (even if it looks ok)

 

i thought they are a dual mass fly wheel so ya counld'nt get them skimmed?

 

If it still has the TD04 turbo on you wont be getting anymore than 280-290bhp max

 

i swapped my duel mass for a 'standard' skimmed unit with exedy clutch and new spigot bearing no issues at all
