Hey guys.

Just got the car back from the welder.. 3" blank cat and A'pexi GT on now.. but I've noticed that I'm only getting around .4 bar.. low boost setting on the Profec is around .9 bar? Am I missing something? Nothing unusual has happened lately, car still pulls hard, and actually I wouldn't know the difference had I not been monitoring the boost guage.

All vac lines seem to be good, there is nothing in-my-face that is wrong. Ideas?

edit: some info that might help?

Greddy boost guage, Tial 40mm WG w/ 7.6 psi spring, Greddy Profec EBC

 

PS: just so you guys know, I'm talking .4 bar all the way to 6500-7000 rpm.. it's not that I'm out of full-boost range.
