Default Can someone with a boost gauge and stock programming please help me test something?
Mechanic says that there's nothing wrong with the wastegate or actuator, but my concern with my boost issues still exist. I am unable to properly control boost with the boost machine, and my boost climbs up towards redline instead of tapering off.

Can someone please test, with the car (225) running the stock program and with the N75 valve electronically unplugged, the behavior of the boost up to redline?

Your help will be very much appreciated. TIA!!

Not quite sure what you mean by that, but if you're referring to safety issues, the boost should only hit about 5psi and I'm wondering if the boost will rise while going towards redline for others.

Default Electronically unplugged will equalize at 5 psi...Not the test you want...>>
But you should try it as it will indicate if The system is pressurizing....

Default It will not...
If your's is it could be:

1) Bad N75
2) Leak in the hose between N75 and Wastegate

Any alternatives to the N75? Current duty cycle is maxed out and doesn't control boost effectively.
