Stock WRX *with good gas and plugs with less than 80,000 km on them * normally pulls ~170 and of course does not audibly det. Cobb stage 2 is usually ~195-205 (depends on supporting mods) but normally with some boost oscillation. This is all with decent fuel. I dont know if I have saved any totally bone stock pulls as that is totally rare, but I have many pulls cars with catback and nothing else (~170-175), and also similar things with shelf maps. We have not had enough **totally** bone stock WRXes come up to have meaningful data (do such things exist ? if so see http://www.rocketrally.com/managed/Article25.phtml and call me). Even our 'sales' stuff is cat-back vs. cat-back + reflash. I can post it all if you want. Its all in the right range. These numbers are also within the same range as all the other DD dynos out there (dyno-comp, ktr, etc.). Stock STi 215-220. But people should remember what matters most is your car vs. before - every car is different ! I hesitate to post one singular example as opposed to lots of sample data because of this.

Banman, the 'cars that det' (there were 2) have nothing to do with limitations of the ECU - it has to do with the map in it and the condition of the car (plugs, cats, etc) and the fuel used. Pulling timing is NORMAL operation for the subaru ECU - it does it when it should ! You can reprogram all of those things - there are no limits on what you can do with regards to avoiding det in the ECU, so actually it is a DIRECT function of the map, the fuel used, and the condition of the playing factors (plugs, turbo and intercooler efficiency, etc.). Dont be discouraged if your car is not doing what you thought it should - the dyno is a tool here to give you insight into that. We have seen cars bone stock (not even bothered to put on the dyno) that dont run right and it has nothing to do with mods - because there aren't any ! But if the car is mechanically proper then the ECU and fuel is definitely a factor.
