I believe it is 16 PSI max boost.

get a boost gauge usually all come 30 psi
and after that hook it up to vacum line and to your boost gauge and hook up the bosst gauge to your light switch in car or you can do many other ways
and get a boost gauge holder
if your not good with installing things clean suggest to go and ask someone who has experience to install it for you
yes sad that they didnt put a boost gauge
did they tell you that they were going to?

30 PSI thats insane!!! I thought it came stock, with a 7-10 psi...30 its a lot of presure... I wonder whats the max psi the engine can handle

RUrep

well i dont know about all gauges but i seen the once that go max to 30 psi
lol
well inorder for engine to be able to handle 30 psi it must be heavily modified and i dont think engine will last long put you know im not an expert and never tried past 15psi in any of my previous cars so i wont know much lol
im new owner of mazda didnt experiment yet lol
and kind of afraid that my only car right now

RUrep

well i meant boost gauge can usually go to 30 psi (showing it on gauge)
lol i didnt suggest 30 psi blah

Mazdaspeed 3 runs 15.9 psi of boost stock.
