We run 92 octane (R+M/2) over here, and 1.1bar of boost would be in the edge of our pump gas.
We can run that kinda boost, but I'll drop the total ignition advance a little just to keep it on the safe side.
I'll take the several percentage points drop in power just to keep the engine safe on the street with the deviation in gasoline (octane) quality.

RICE RACING is da man to talk to when talking about that supplemental injection stuff.
In fact, there's a good thread in another section somewhere where there's a lot of good numbers for this kinda stuff.
I personally don't touch this stuff, so I'm not qualified to answer such questions.

Just looking at your graph though...
You're losing around 20 lb-ft (or more) in that "dip" section.
That's a pretty significant amount of power, especially in the middle of your power band.
It would be nice to fix it and gain back that lost power.

I have one more question, are datalogits and Wideband kits a good thing to have or is it a case of Not clever in the wrong hands. TBh i proberly wouldn't like to touch the map myself buy i don't like the idea its been set up by some one who hasn't tuned out some thing that Ovious and i'd like to see what the rest of the maps doing.

I'm not a P-FC / Datalogit tuner, but the Datalogit does offer additional features that the P-FC Commander doesn't.
It looks like it unlocks a bunch of auxiliary maps and allows (more) datalogging.
Datalogging can be of great help for tuners, or if you do a lot of adjustments (driving by) yourself.

It still comes down to the capabilities of the tuner...
You can give the best tools to a crappy tuner, but it still won't help if they don't know how to utilize those tools.
A good tuner can get by with barebones monitoring (i.e. gauges) and tools, and still be more effective than the crappy tuner.
