wont build high boost??

[shanksRX-1]

Our rx-warrior wont build high boost on high. We flipped the switch and put in the right pitot jet but it will only build about 5-6.5lbs of boost. Im thinking there might be a blockage in the switch line or maybe a boost leak?? Anyone got any other ideas before we start ripping into it???

when i flipped my switch last weekend it did nothing,stayed at 6lbs either way.ordered a manual boost control.

Exhaust leaks, exhaust leaks, exhaust leaks...
And the boost control switches not bleeding enough boost from the wastegate diaphram... (opens at lower boost)

also just saw where someone couldn't build boost and it was a faulty boost gauge... The sled was actually making too much boost when dynoed and they thought it wasn't making enough according to the tell tale gauge...

Your tube is pinched under your seat, make sure the tube to your swtch is not blocked

I had a switch, it was very incosistent, throw it away and get a proper MBC like the Hallman Pro RX or even better an electronic one.
