i think i'm having boost issues

I am running quick trick's looney tune, and only seeing about 20-25psi of boost. Is this normal, or do I have other trouble?

Stud tune or stock stud tune? Depends on the load also

Did it ever hit more than 20-25? Check your map hose going into the intake manifold for cracks or anything

Where are you reading boost from? If you are reading through the obd2 port it will be low, most tunes have a boost foolers to keep the ecm from opening the vanes of the turbo for over boost.

If you are reading from a mechanical gauge then you may have a boost leak somewhere, check all your boots for rips or cracks. It should be pretty obvious it you have a leak somewhere.

What does the MAP hose look like? And where abouts is it located?

Alright, I checked map hose, and everything seems to be ok. Could it possibly be a map sensor?
