Be patient
I've been doing some VCDS logging recently and noticed that the boost requested is good and high. I spoke to my tuner and he said that GIAC have been able to give this high boost map for stage 3 cars for a while now. He mentioned that they have to do some quite tricky mapping of the ECU by scaling to do this and that
they will also be doing this for other levels of tune.
Requested is really good at 2680mb, whereas most other maps do not currently provide this.
Here is a quick pic of my VCDS log downloaded to excel. I have the original cvs files too for anyone who wants a closer look.
I run a boost controller now, so my actual will go slightly higher than requested.
