WRXRebelT1i Posted July 23, 2013 Share Posted July 23, 2013 Hi everyone, I previously owned a bugeye WRX for about four years and I am looking to buy another Subaru. Specifically, I’m looking for a 07 and up Legacy GT. I recently test drove a 07 wagon with the 5eat. My main question is about the Si-Drive system. Does setting it to intelligent mode limit horsepower significantly? The engine seemed to pull strong in sport mode, but I did a 2nd gear pull in intelligent mode (forgot to switch it back to sport) and it felt gutless, almost like the turbo wasn’t spooling at all. I just want to make sure the lack of power had to with the Si-Drive system being set to intelligent mode and not this specific car having a huge boost leak or something. I also have a few questions about the wagon now that I’m leaning towards this configuration. Was the GT wagon discontinued starting for the 2008 model year? Is the wagon’s wheelbase the same as the sedan? I also remember that a few years ago people were talking about a high engine failure rate (rod knock) in 2009 model year WRXs. Should the 09 LGTs be avoided for this reason as well? Thanks for any advice; hopefully I’ll soon be a Subaru owner again! Link to comment Share on other sites More sharing options...
spicytuna Posted July 24, 2013 Share Posted July 24, 2013 Can't answer the wagon related questions but there's definitely a night and day difference between the SI drive "Intelligent" and "Sport" modes. Link to comment Share on other sites More sharing options...
trhull Posted July 24, 2013 Share Posted July 24, 2013 SI drive controls throttle mapping (throttle by wire). Intelligent makes the throttle response slower and also does not give 100% throttle which is why it felt slow. "S" mode is supposedly the most linear to actual pedel movement. "S#" basically shifts the map left so you get full throttle before you actually reach full throttle with the pedal; this gives the illusion of more power.

mass-hole Posted August 6, 2013 Share Posted August 6, 2013 I wanna say "I" limits it to like 70% throttle or something based on the little graph that you can display on the dash. Im not sure how acurate that is though. Sport and Sport# both go to 100%. Link to comment Share on other sites More sharing options...
LatentWagen Posted August 16, 2013 Share Posted August 16, 2013 SI drive does not just limit throttle response. In intelligent mode it actually limits boost (and TQ) as well. If it feels good in sport, keep it there. I almost never use the intelligent setting. LW's spec. B / YT / IG Link to comment Share on other sites More sharing options...
dgoodhue Posted August 16, 2013 Share Posted August 16, 2013 07 was the last year for the US GT wagon. Link to comment Share on other sites More sharing options...
dgoodhue Posted August 16, 2013 Share Posted August 16, 2013 Some early 09GT had early engine failures. They are 5 years old now; IMO the problem motors would have failed by now. Link to comment Share on other sites More sharing options...
