Isnt the stock boost 15psi on a 2010? My buddy is only boosting to 12psi, and the dealer is telling him this is all he gets and that is what it suppose to be. I am sure that mine boosted to 15psi....

can anyone help me?

 

There is no set boost as far as psi on the stock tune..

 

the car makes 260tq no matter what boost pressure. i remember last winter it was like 0 degrees out and my car was boosting 9psi. lol.

 

my car was boosting 12psi when it ran a 13.5 stock...it was boosting 19psi when it was running 14.0s in the summer heat lol. Like what was said...the car limits torque and it takes less boost to make the same torque in colder weather.

 

my car has always boosted 15psi no matter what, except in winter in colder weather, it slowly moves from 10psi up to 15 psi when it hits higher rpms.
