Helping a buddy can’t lower boost.
« on: May 05 2019, 02:35:38 PM »
Car has had a new turbo 6262 added and a Lorenz controller TH style downpipe.
Puck moves freely and all hoses are new.
Installed a powerlogger for him and said I would help setup a decent tune in it.
Power logger and boost gauge both read the same
28-29 psi. (Car ran like a raped ape)
Cranked the boost controller back as far as I could no change.  Loosened the actuator 1/4 inch there was slack no change. Unhooked the boost controller went tuner style no change.
I might try a lighter can if I can find one local.
Boost pressure not getting to the can perhaps?
Any other ideas?

I tried that Steve no change.
That was was what made me think there is no boost getting to the can
One thing I did not try but should have was unhook the actuator.

Make sure the hose isn't pinch off or the controller is installed backwards.

first trying pumping a little air with a mitey mite or something similar that is around 20 psi and see if the actuator is working...and then your idea of removing the arm

Ok so far tested the can with air it seems to work as it should.
Looked at the fitting and casting of the turbo they seem good no blockage
A test with the actuator disconnected is in the works. 
This downpipe was on the old turbo worked well then.

I did not install the turbo so I’m not sure. Once I hear back on the test with the actuator off I will have to pull the downpipe and see hope it’s not that hate pulling apart a brand new turbo to port the exhaust.
I got the exact turbo on mine with an external gate I can get the boost down to 14psi.

Wire the puck open and drive it. See how much boost builds with the puck wired open. If it’s above 10 psi, you need to open up the hole.  Helps to blend the turn to the waste gate hole as well. My 6262 with a .63 housing did the same thing when I first installed it.

I think I pull that housing off and see if it even has a hole.

If you have the right tool, you should be able to do it on the car
