Superchip.......Oh Dear!!
Think I see where you're going there - PPP is, plus the exhaust, basically a Superchip in context, i.e. "one size fits all" In this guise it's fully Subaru approved! (Got a feeling Prodrive may have tested and proved it possibly a bit more than Superchips?)
I would bet that the answer to your question is NO!

PPP is what i was thinking, also a re-map but with subaru approval. What if a green filter was fitted, revolution back box and a ecutek map you'd still get to a power level in line with the PPP and presumably within Subaru's tolerances for the engine...
Anything above PPP levels without internal work i'd be worried about.

The so called Superchip interfaces to the the MAP sensor circuit and is basically a Fuel Cut Defender. This adjusts the signal seen at the ECU, so that the ECU thinks the car is achieving slightly less boost than it actually is.
Therefore combined with the bleed valve, that is also provided, slightly higher then stock boost can be run. IIRC they used to set a Impreza to 16psi.
This is fine in principle and the ECU should be inteligent enough to adjust the fuelling to suite, so AFR's should be OK.
What is does not do, is make any adjustments to the ignition timing. If the ECU detects detonation it will pull timing from the advance map. But it can only do this as far as the advance map allows. Once the ECU is running on minimum advance map values it can only use the base map and hence detonation will not be removed.
I have heard early WRX detonate at 14psi which is only 2.53psi above standard, so I would be very cautious about running a Superchip or any other form of mechanical boost control above 14.5psi/1bar without getting it checked.
FYI Z4 ECU equipped WRX are slightly more tolerant compared to the earlier 2C, W6, U8 and W9 ECU.

Even with a stock cat? I was thinking about getting that kit and having a map to PPP because it is what i consider a 'safe' level (i can see pslewis' point about unreliability) but i was thinking you could do that lot for half the price of the PPP at least.

I agree with Harvey here.
My first Subaru was a UK late MY96 Turbo. Back 10 years ago aftermarket parts for Subaru's just didn't exist and I bought a second hand Superchip for it, paid £180, and used it at 18psi for 3 years before selling the car.
Nearly 10 years on, the car is still local to me, it's now done 130,000 miles with no problems and the superchip is still fitted.
Superchips were heavily knocked on Scoobynet and it's original forum, but mostly by people trying to sell newer items for their own companies.
I can't honestly remember reading of anyone blowing up an engine using a properly set up Superchip. Most of it was gossip.

Why were they marketed as re-mapped 'chips' when they were nothing of the sort? Several hundred quid for a FCD and crude bleed valve.
