I don't have any personal experiences with perfect power, but a friend of mine who does all my car work for me and a whole bunch of other guys out in Denver, CO is running perfect power from rallitek i believe on his Turbo'd Impreza L and he is having great results. He told me its great for beginner tuners and easy to understand. Also, 2 or 3 other pre-2002 tubo'd 2.5RS are running the perfect power out in denver and also have been saying great things about it. I believe an STi owner was thinking about running one. Other than that, I can't really help, good luck...

A: its a piggy back it "fools" the ecu in to modifiing paramaiters vs just changing them
b: the sti ecu is very very complex
c: many many more reasons (cutting)

look around the the forum the only people that are using the PP are people that have been hood winked into it, for lack of expirence or options

Using an offset device like the Perfect Power on your STI is not a good idea. Offset fueling is a very difficult proposition with an ECU that has significant dynamic learning in both timing and fueling.

We have removed many many piggy back devices (Unichips, Perfect powers, Exde, eManage) and replace them with reflashes with significant improvements. If you are serious about getting reliable power with your car, you should consider either a reflash or a UTEC. Given that you are local, you should stop by and talk to one of us. (see our address on www.pdxtuning.com, we are right off 217 and I5.)

You can really only get away with it in open loop. So you have to ensure the device is only modifying the fuel signal (in this case, MAF voltage) when in open loop.

Otherwise, the ECU adjusts its LTFT and the piggyback ends up doing nothing.

I had an SMT6 on my last car (naturally aspirated) and it worked really good for cutting fuel at WOT, since the stock ECU wanted to run 10-11:1 which was ridiculous for NA. But I couldn't touch the low load (TPS) sites.

But using TPS for load on a turbo engine is probably not appropriate. You probably want to use MAP. And then it becomes hard to only map when in open loop.
