Check Engine Light Code P1103

You cant lower the boost. The wastegate can only go down as far as what its set at stock. Example: if you have a 15psi spring in an external WG you cant set it below 15psi.
I think I had this same code once and one of the lines going to the WG was crimped.

I didn't know that. I was going off what my autometer cobalt boost gauge reads
