Up my boost from 1.1 bar to 1.3 bar

Well, since my logs are showing that things are going fine, I decided to up my boost to from 1.1bar to 1.3bar. I did this by changing the parameters in my Blitz SBC-ID boost controller.

Here are the changes: (Channel1)
For 1.1bar
Set: 40
Gain:15

For 1.3bar (with this setting, at 4th gear pull, it reached a max of 1.36 bar)
Set: 58
Gain: 20

Note: Boost readings above are from SBC-id itself.

From blitz sbc-id manual:
SET
Shows the boost ratio or boost pressure setting

GAIN:
Ratio of 0-100
Gain controls the boost response. The high the gain setting,
the faster the boost response will be. Stock turbo charged
vehicles with actuator type wastegates will usually use a gain
setting of 5-15 percent. External type wastegates usually
requires higher gain setting.
WARNING - High gain setting might cause boost spikes.
Note: Each channel can be set to each individual gain setting

At 1.1bar my IDC maxed at about 90%, it's the same at 1.3bar.. not much difference - which is strange right?

Here's the dyno graphs
on 27th July at 1.1bar
on 3rd Aug at 1.3bar



Lower HP at higher boost? Well, not exactly right coz I had my wife and son in the pull on 3rd August. After adjusting for weight, here's what I got (about 10hp gain) ..something's still not right!:


I'm too tired now. I'll post updates on another day.
