Hello tuners,

I have been using my first Stage1 work for awhile on my stock E39 525D, and was happy with it. Car's acceleration improved much, accelerator responsive, fuel economy +- the same, no smoke...

Haven't posted my setup here, but I am really curious if I did it right, and were there no mistakes.

The reason I am asking is, that I've just changed my stock turbo to GT2260V from X5 3.0D, want to push more juice out of it, and wanna know if I am on the right way.

Could you guys check my work with your comments?

SOI, duration, N75 are untouched, because of my lack of knowledge.
