What do people think is the most boost i can run without going silly/unreliable. Brief spec is 93 wrx ra, Scott taylor chip, full decat from turbo, large K&N induction kit, cold feed, fuel cut defender and a dawes device(both unfitted), LW flywheel and clutch from API fitted last month. Engine is in good order and always serviced etc.

I am about to fit a boost gauge, knock link and a lamba link.

 

see what your getting first with the boost gauge
