Default Not hitting target boost

I'm using the stage 3 vf30 93 oct map and am not hitting the target boost. I'm new to the accessport and am not sure what to adjust and by how much if that's my problem any help would be much appreciated.

Here is a 3rd gear pull

What restrictor pill are you running? Can you list all your mods?

Primarily your problem is going to be a missing restrictor pill. If you have one in there and it is the original OEM one, then you are fine as the map is designed for the stock pill.

I think your issue of low boost is likely that the aftermarket TMIC and headers are getting you outside the scope of the OTS map. If the pill isn't missing, then you likely just need a custom tune for your mods. The SPT intake is also not the compatible intake for the map - although this will not impact boost appreciably, it can cause load errors which can impact fueling and ign. timing.
