2001 USDM Subaru Impreza Wagon Auto WRX - Canada Remote Tune
Posted: Sun May 27, 2007 8:33 pm
I tuned this car sometime back last year in Canada Remotely.
Here are the results:
A stock Auto, because of the tranny and its loses, does 130-140whp at 13.6psi. Unfortunately, I do not have a stock run, since this customer came in with a Cobb Stage 1 Map, which I better and he preferred my tuning, since the power was smooth and flat and no audible pinging after 5000rpm.
The stock map, like any other Subaru, make torque by 4000+rpm and max HP around 6000rpm. Any WRX/STI owner knows this. After tuning, torque comes in early and the torque curve is even flatter. All tuned WRX/STI can witness to this.
We also believe the car had a leak. It could be a crack wastegate housing. Even in stock, a sudden rise in pressure cause a drop. You can see this on the graph.
Road Boost response @ 16.5psi
In Gear Acceleration:
30 - 50mph = 3.1 seconds
40 - 60mph = 2.9 seconds
50 - 70mph = 2.9 seconds
