Loosing Boost

[viewtek]

Hi All,

I Installed a boost controller (manual) that I had on a previous car so I know there is nothing wrong with the controller. Im set to 13 PSI and when I am under full acceleration boost drops off, If my foot is only half way to the floor boost sits at 13psi. Any ideas? Also were is the stock boost solenoid? Its an R32 GTST. Also I have read about the high boost mode mod and was wondering were the wires are located that i need to ground.

thanks

r32's don't have a solenoid, they just have a 10psi wastegate actuator.

at what rpm does the boost start to drop off, and what does it drop off to?

It starts dropping off around 4500 - 5000 and drops to 10psi
