Gruppe-S is pleased to announce the release of our Ecutek™ reflash for the EVO 8.

With our years of experience tuning high-performance race vehicles such as the WRX US-Touring Car as well as numerous Rally and drag cars, we have perfected the art of tuning a high performance vehicle and extracting the maximum power without compromising safety.
We have found through months of testing that the Ecutek reflash is far superior to reflash systems that many of our competitors offer. The Ecutek reflash allows for far greater tuning flexibility, tuning stability, and additional features such as 2-step, effective scaling for larger injectors, effective scaling for larger MAFs, etc.
In essence, the ECUtek reflash is powerful and flexible enough to accommodate a wide range of EVOs, from cars that are completely stock to cars that are heavily modified.
Presented here is our Stage 0 map, which is developed on a COMPLETELY stock 2003 EVO VIII GSR. The only modification we have made is to the ECU, and a minor modification to the boost solenoid.
Gains of 18.2whp were achieved without sacrificing any low-end to midrange torque on CA 91 octane. Rev limit was increased, and AFR remains at an ultra safe 11.2 : 1, even at 95+ degree weather (it’s hot on the dyno!). Did we leave power on the table with an 11.2:1 AFR? Yes we did, but our tuning philosophy is maximum power and maximum safety.
In essence we have developed a map as the stock EVO should have been from the factory – a 300HP car out of the box on California 91 octane pump.
We will be releasing our Stages 1, 2, and 3 maps shortly, which will range from basic bolt ons to a GT30R. More dyno graphs will be posted soon...stay tuned!
Below are the before and after dyno graph results (stock Evo on CA 91 octane): :)
Before:

After tune:(much smoother power band w/ conservative AFR)

Comparison graph:(smoother power band and great tq on high rpm)
