i have been chasing a boost problem around since i got my FD ~3 weeks ago. its full sequential; someone did the simplified seq. mod. all the actuators are hooked up and functional, all the vac lines are secure, and afaik i sealed up all vac/boost leaks...
my secondary turbo is leaking oil out of the compressor so i'm guessing its on its way out, but even on its way out it will boost.

here's my boost pattern (with no pills in the wastegate lines): 8-6-3
like i said, i verified that all the vac lines are correct and secured, all the actuators and flappers work, etc. whats next? i'm about to send this thing to non-sequential land, but i LOVE the instant boost from the primary turbo in the low rpms.

 

any updates on your situation?

 

check your TC solenoids or the ground wire going to the TC solenoids or TC actuator
