Ok, like I said I had some time to mess with this stuff yesterday and mess with it I did; got a bunch of good data.

So first I loaded the HWG map and did a pull in 3rd here's the datalog:
Still under boosting, not much change besides the higher WG duty and slightly later peak boost

Then I shortened the WG arm by 1.5 turns while still running the HWG map and soon realized that it was way over boosting. I flashed back to regular stage 2 and recorded this pull in 3rd:

It peaks just under the target of 16 psi which I was happy with until I put down throttle in 4th and noticed spikes to almost 18 psi and fluctuations as a result shown in this datalog:

To counter the over boosting I flashed it to the LWG map (still has the shorter WG arm) and did a pull in 3rd:
The boost spikes to a little over 16psi early and there is some light fluctuation that I didn't really notice while driving.

I'm thinking I should lengthen the WG arm by .5 turn and continue to run the LWG map? Or is there a problem here that can't be fixed by just messing with the WG?
