hi, i have a 2.9 pulley with overzised tensioner pulley and i only see 12 psi, with the 3.1 pulley i see 12 psi too, i live at 6600 feets, so i dont know what happend, the car is not nocking
thanks for all

 

Do you have a tune for the 2.9 pulley?

 

im running stage 2 tune

 

The boost wont drop from the tune, unless you had some sort of boost reduction. Which stage 2 tune? GM, ZZP, OTTP?

Your elevation will affect your boost level as u suggested. What temp are you performing these boost level tests at? Temperature will affect output as well.

 

this is my last log

 

I don't see a log.
