YEA man i have the agp billet wga and no over boost codes yet.I have had it on there for a year and nothing.I peak at 17-18 and hold 15 to red line. I belive it will go away when you get the stg1.But thats weird that some guys get that code.ONe of my friends never got that code ether.But he did get the code for not haveing a cat lol.It took a while but it did come on after about 5 months

 

What are you peaking at and what do you hold to redline?

 

i had the same problem. i have an agp wastegate and turbo xs boost controller. All i did was remove the red intercooler hose and put a cap over it. unplug the battery for 10 minutes start up your can and mine hasnt thrown the code again. my friend had the same problem with his wastegate but were boostn around 18 psi with a little drop to about 16psi.

 

Yeah you can just remove the tip sensor line (red/white). It takes PCM controlled boost out of the equation. By doing this your running solely off the control on the WGA, not the PCM AND the WGA at the same time.

I have my white/red tip lines removed and capped, my boost is controlled completely by the Greddy EBC. My computer has nothing to do with it.
