Default Stage1 +sf underboosting?

Just got the Cobb sf intake w box and on the stage1 +sf acn 91 map.

I currently am using the accessport to monitor my boost cause my defi hasn't come in yet.

on the map notes it says peak boost is 16psi. The accessport is reading 13.8-14psi going to 6500rpm 1st-3rd gear.

Just to make sure.. I do go on boost and not boost target on the ap to monitor right?

Only mods are sf intake and nameless axleback exhaust.

Do some 3rd gear pulls and log the default parameters. Boost target is what the car ideally wants to hit and that is your compensated boost target, it is adjusted by intake temp, altitude. Boost is what you are actually hitting. TD boost error is the amount of lbs you are off from your target boost. I would log boost target, boost, and TD error to see what the car is doing.
