Losing boooost D1 Procharger Hi guys
How are you all? ����
I need some help started to get crazy ����
I'm facing some issue and got stuck need some advice !!
I drive a 2001 Trans am ws6 ls1 6speed
Modes
D1 Procharge (10psi) , AFR heads and cam, Bolt tons,
I toke the car to the tuner, where the problem started in the dyno
Loosing boost from 10 psi going slow to 5 then in high rpm 0 psi.
My tuner said to do a boost leak test, I found the blower it self leaking and 2 injectors and 1 clamp is damged all of this is fixed. And here where it's makes me go crazy ����
Took it back to the dyno and still losing boost in 4k RPM from 8psi going low 0psi !!
So What do you think guys.
Nitrour is the best easy And cheaper ����
thank you in advance

i guess belt slip. Do you have a front mount intercooler and what bbv , or the procharger twins
Are you on the stock procharger bracket ? 6 or 8 rib
aster bracket or sdce ???
My main guess is belt slip

I would look at your boost/vacuum line going to the proflow valve. Since it is building boost, then all of a sudden it loses it, sounds like you don't have an adequate airflow going to the blow off valve.
So what happens is once the vacuum goes to zero, you start building boost, but only as much as the spring in the proflow will hold, once it opens, it let's go and the boost drops.
