so im sure this is a talked about topic and i hope im not beating a dead horse. but what kind of pressure are you boosting and holding on a gear pull. im asking because i just installed a corksport TIP and new CS recirc hose and i think i may have a leek somewere. i also have a MS CAI and a Forge BPV. if memory serves me before i installed the TIP i had a peak boost of 16psi but i dont remember if my boost was holding or fading. after the installation of the TIP im now getting about 15 psi but i noticed on a 3rd gear pull the boost pressure would drop to about 12-13 psi. and about the same in 4th. is this normal for the MS6 or did i develop a leak along the way? any input would be great guys.
