Setup is a 14b on a D15. We started out running 7lbs with the stock wg setting. It held 7psi but over time we started noticing that it would drop to 4 or 5lbs. So we put a boost controller on the system and it held 6lbs for a while. It used to drop like this before we put the boost controller on and now its doing it again. 1st gear only like 4lbs 2nd gear 7lbs then once it reaches 7lbs it starts to drop down to 4 or 5lbs 3rd gear holds 7lbs, sometimes even 9lbs then slowly drops to 4 or 5lbs. This doesnt happen all the time, sometimes it actually holds 6lbs steady. I attemped to pressure check the system but Im going to have to make a really good coupler so I can just pressurize the charge lines. (Any tips/ideas on what you use here would be great) I took the external wg and pulled the actuator and it would suck air in when I pulled on it and would push air out when I let go so I dont think that its the WG. Im pretty sure that its a boost leak but Im looking for any insight,

yeah man, Im getting the same problem..bump

 

TTT for some insight....

 

anybody?

 

Nobody has any insight on this?

 

I'm having a similar problem, except I hit peak boost(11psi) and then it will jump to almost 20 and stay there. I was thinking it was the diaphram busted, but I'm not sure.

 

I searched for "leak"
