help massive boost spikes

[bangin]

hey guys im running standard turbo with pfc with boost control. im getting massive spikes today like when i run .70 or .90 bar it spikes to 1.5bar! my duty cycles are 48% for .70bar and 60% for .90 bar and i think they are ok because it never spiked this bad. yesterday i installed a z32 afm and don't this is related. i do though have a boost gauge t- pieced into the pressure sensor hose of the boost control and checked all hoses for the solenoid and sensor and all ok. i'm thinking the boost solenoid is stuffed? what you guys think?

can't really help too much.

Maybe reset the boost settings so the powerfc re-learns.

I thought this effected the way the boost controller worked?

errr, don't u have to re-do the whole map when you put in a different AFM?

Firstly u have to change the afm setting on the pfc to Z32, and then yes it will need retuning as the z32 will be sending different voltage signals to the pfc that the stock afm.
