Mate I'd take it real easy, I expect you'll be getting boost spikes / over boosting all over the place, the last thing you want is the engine to go pop, take it easy until you can get it checked out...
good luck

to be honest there is no spikes or over boost......i have full response on all gears
there is no lag whatsoever.........the car is running 100% better than when i had the tdo4

A classic Impreza would need an aftermarket ECU like the Apexi PFC or something from Autronic or perhaps Hydra depending on your exact requirements.
The OEM ECU uses a MAF sensor which will compensate for a change in your engines volumetric effieciency and the knock control should sort out the ignition timing. However the degree of change is limited by the configuration within the ECU and the standard knock control does not pick up det unless it is quite severe.
Regardless of how good it feels don't assume everything's alright, just ask Frayz......the first time we logged his car with just a decat exhaust system and panel filter it was pinging away above 5500rpm but it felt like it went well, had this been allowed to continue say hello to a hole in the top of your piston.
You may well be in luck with yours, the standard fuelling system runs v e r y rich so the increased airflow from the TD05 maybe balancing ratio of air to fuel to a more suitable level but without logging with a wideband you'll never know.
I'm not here to put the frightners on you, just to offer advice in support of the club and it's members. Don't take my word for it, ring around and speak to some of the other mappers for their opinion (although stick to the one's that know what their on about and ensure you speak with the mapper themself and not just a person from the company they map for)
If you choose to ignore everyone's advice above all else fit a Knocklink - £140.00 and it may well save your engine - this should be the very first purchase of any Impreza owner intending on any modifications..........

KnockLink
There are prettier versions about if you think this is too combersome or the board can be removed from the box and the leds mounted remotely.
If you around the North Weald area pop in (call first incase I'm out on the road) and I'll stick the wideband on it for a quick check on the fueling

these do look pretty poor as standard, but with a bit of thought they can be installed quite nicely, see below
