possibly be the boost gauge out.. and i know cold weather probably has something to do with it and elevation.

but i seen last nite.. at about +3 out.. I converted my boost gauge which is in KPA's which is suppose to me more accurate.. to PSI.. and that i was hitting 110 to 115kpa's which is 16psi at 7000rpms.. seem right?

mods are injen intake and stage 2..

 

yeah, i was seeing 16-16.5 with just a stage 2 once i did the airbox mod. The CAI allows better flow, especially when its cold out. Also, if you're still running your stock exhaust, it restricts flow and will keep higher boost pressures.

 

100kpa = 14.7, which is one atmosphere.

zero boost.
