Glad you found it to be "just" a bad new pump. I'd stick with the Bosch 010 myself.
As an aside, I replaced my pump way back when and noticed no improvement in IAT's. After splitting the I/C circuit from the cooling circuit, I had the same lack of results. No difference. Then I added remote reservoir and sprayed water everywhere under high boost. That's how I found my leaking intercooler. I'm not saying yours is leaking just that when you don't get the same results as everybody else, there's a reason to be found.
