Subaru impreza Wrx Sti Hawkeye Stage 1 340Ps

The Subaru Impreza is a compact family car that has been manufactured since 1992 by Subaru.The Impreza (also Impreza WRX and Impreza WRX STI) is a major rival to the Mitsubishi Lancer (and Mitsubishi Lancer Evolution).This 2006 2.5l European version Hawkeye (280ps) is about to get reprogrammed in our awd Mustang Dyno.

With the addition of an aftermarket exhaust system with a race catalyst and intake system our client asked for a safe stage 1 tune which will not compromise anything outside or inside the engine in any case.

The decision to install a stage 1 software by the obd port was made and our stage 1 was immediately flashed and dynoed showing good and stable numbers in our awd dyno with only 1.5 bars over-boost and 1.3 of constant boost pressure using 100 octane fuel.

Here is our dynosheet with a perfect curve on this 2.500cc engine using stock turbo and injectors up to 7.500rpm.We never had a stock measurement of this car as it came with some spark plug issues which were fixed in a different timeline.

The final numbers? 338.9 PS and 460 NM without any hesitation  with only 1.3 bars of constant boost.
