Boost Control Error

I am having a problem trying to hit 26psi, I can only hit 22psi.  I am using VSS to set boost to 26psi and it wont go above 22psi.  I know it could be that i need a different wastegate spring but I am just curious because when i set the boost to 26psi the parameters say boost error -22.6psi.  anything i set the boost level to under 22.6psi it works perfect and shows the correct value in the Boost error parameter.  I cannot find anywhere to change this boost error value to go higher than 22.6psi.  It just seems that I have a limit set somewhere for the boost error to show this value.  Please help me out if anyone has experienced this.  Hopefully I am just missing a setting somewhere.

Thanks

You need to look at what

You need to look at what wastegate solenoid duty you're running. It doesn't matter what your target is if you're maxed out on wastegate duty - you'll never hit your target.

Thanks for the response.  I

Thanks for the response.  I will log duty cycle next run but I just want to know if I can ignore the boost error not showing what I have it set to.  If I set the boost to 10psi it shows -10 for error and if I set it to 14 it shows -14 but if I put it at 26 it says -22. Tried 28 and it still shows -22.  Just want to make sure before I get back on the Dyno if this is something I should be worried about otherwise I am just putting a different spring in the wastegate to make sure I can get to 26psi.

 

Thanks

Unfortunately I can't provide

Unfortunately I can't provide you with additional support since we no longer support the Series 1 but you should know that any discussion about boost control should include wastegate solenoid duty.
