I changed it because everyone told me I was wrong, and I believed them. But when two people that actually own/have owned one of these cars tell me it was probably only running 260bhp, it leads me to conclude that the rest of the posters were talking crap as usual (based on it not sounding right probably).
Other people who have responded have owned PPP'd newages. Not just 2.
SN has enough members to get a more balanced picture.
The PPP kit is 305PS which is 301BHP. When i got mine on a dyno it was more like 298BHP.
In my experience the PPP power claims are never made. These cars are typically 295/296 bhp with PPP.
296bhp 313lb/ft all runs were consistant ie lowest 293bhp highest 296bhp and it was a warm day too..
While the PPP claims 305bhp, in reality your probably looking at a little less - mine recorded 297bhp shortly after I got it
Mine went from 298bhp to 340.6 and was dynoed at Surrey rolling road
That took 2 minutes on SN...those are PPP blobs and seeing as each owner has remapped and now have a higher bhp, they have no reason to tell porkies. Mine was 298 stock, I should still have the graph somewhere.
The PPP not making the 301bhp(305ps) was addressed officially, the PPP map monitors the inlet temps unlike the standard STi map:

Technical Service Bulletin
Subject: PPP Tests
Model: Sti
We are becoming increasingly aware that owners of the above vehicles and others equipped with a PPP are taking their vehicles for a rolling road test and being advised of varying results on power output.
A rolling road test is very difficult to rely on to give an absolute figure of the output an engine is producing particularly when it is only possible to measure at the road wheels instead of the flywheel. There are also too many variables in how the test is undertaken including how much air is being blown at the car, which is rarely sufficient and the temperature at the intake/intercooler.
As a precaution against engine damage, the PPP is designed to reduce boost if the intake temperature becomes too high and this occurs as soon as 40 degrees is achieved. This can occur for example whilst a vehicle is parked for no more than a few minutes, even when the ambient temperature is low. For example, in a 4 degree ambient the intake temperature can rise to 51 degrees after 11 minutes with engine merely idling. This could easily happen prior to a vehicle being rolling road tested unless it was being monitored properly to ensure everything had re-stabilised, otherwise the engine power data obtained is unrepresentative.
When our supplier undertakes tests on rollers the figures quoted for a Sti (302bhp/305ps) are consistently obtained but this is only after making absolutely certain everything is as it should be before commencing. If the intake temperature is too high, a Sti will typically provide indications of only 285bhp/290ps very easily. An owner is then of the impression that his vehicle is under performing!
If you receive a complaint of this nature, the owner should be in a position to provide a rolling road test data log. Should it be apparent that the test was carried out with intake temperatures at or above 40 degrees an owner should be advised why the test results show a lower output than anticipated.

The STi is 260bhp from the factory. There would have been blood if you paid for the PPP and nothing changed.
As far as running 95, I couldn't tell you. Mine never had anything but Optimax. I'm sure I've seen a few threads on SN with people proclaiming that you are wasting your money running SUL, Prodrive recommend 97 but you'd have to look more into it yourself.
But, like I said earlier in the thread, the car doesn't sound the best example from the way the dealer is looking after it.
edit - how do *you* know the car is PPP'd?
(that's a sort of biker logic if you like).
