installed BMS DCI/Evolution divider pipe/Forge DV's

Install seemed quite easy and straight forward but after I went for a run, the performance was uninspiring. There was no low end at all. I then got a CEL. When I got home, I did a BT scan and this is the code:
30FF Exhaust fume turbo charger low side.
Something must have gone wrong with the install. Any ideas?

boost leak! check the connection to the throttle body on the charge pipe as well as on the dv's (where they sit on the charge pipe).

Boost leak. check your connections again. check the forge dv's. verify the pistons are moving inside.

Thanks! I figured as much. How do I know if the pistons are moving in the dv's? I installed the yellow springs and made sure the pistons moved before reassembly. The divider pipe end that goes to the throttle does not seem to be as tight as the stock pipe. It uses the factory o-ring to secure the pipe. Thanks for the help guys.

thats the downside of that particular charge pipe, but its quite popular so I guess people are having good results securing it with that mechanism

To the OP, did you pull the rubber O-Ring out from the inside of the OEM charge pipe where it connects into the throttle body? There's an o-ring in there that needs to be transferred over to the ER Charge Pipe. It sits INSIDE the oem cp inside one of the grooves that connects to the throttle body. Not talking about the metal clip that holds the cp to the tb. Ask me how I know...lol. I just installed my ER CP with the Synapse BOV.

OMG, lol. Totally missed that step. I kept on thinking it was the metal clip to the throttlebody. I intalled the o-ring and now it pulls like a mofo. Thanks!!
