Hey,
Last year, I could easily build boost to 15PSIG and on the dyno get up to 17PSIG
However, Lately I max I can seem to get is just a hair over 14PISG.
Havn't changed anything,

My air filter was new less then a year ago, K&N that
came with my ZZP Intake. After that install I was boosting
to the normal 15PSIG

Could it just be dirty plugs?

Should I even be concerned that anything is wrong?

 

i'm in the same boat. but i peaked around 16. now i'm doing 13 or 14. i've been running the canned ottp tune since last summmer and moved to colorado from texas. but i'm prett sure i did a wot when i got here and it read 16. but i may be wrong.

in for answers

 

Welll youve got elevation working against you, so that would make sence.
Im in the same place geographically. The temp is a little warmer, but even
last summer i could still push 15PSIG.

I heard there was some kind of Boost Solionid mod for the LSJs,
but when I searched I didnt find anything useful, mostly LNF stuff.
one said take off the bottom hose... but there isnt a hose there normaly,
just a filter over a vent port.
