Nytro/MCX Trouble

[Klutch]

I have a Nytro with a MCX turbo and it's the earlier version so it has the bigger efi box with the external barometric pressure sensor, fuel pump and regulator. The turbo was set for 11psi at 6000 ft and that is what it read on the gauge. Now I take it out at 2000ft and stab it to 3/4 throttle and the gauge reads close to 25psi. How is this possible?? The only thing I've done is move the barometric pressure sensor up a little higher. Any help is appreciated. Thanks, take care.

Are you sure your wastegate is moving? I have had signal line to my boost controller freeze from moisture and lost all boost control. Would hit 23-24 psi instantly. Move your wastegate by hand to ensure it isn't stuck and check your line to the wastegate actuator to make sure it is clear and free.

Mine did that and I found my TCV (the little electronic boost T) was stuck wide open
