18psi is a stretch. Must be sea level. If I try I can hit 16psi, but I average 10-14 in the warmer weather. Dead of winter I lucky to get 7psi. Lol

even when i had a air intake on mine (now just modded stock airbox) i didnt see over 12, and an intake on every other turbo car i've had bumped the boost up about 2-3 psi without a tune.
