XPT Stage 2 - 2006 WRX Manual
[XPT2201X]

Excellent product. Very easy to install. I installed this on my 2006 WRX with 3" TBE which was running with no tune.

XPT stage II tune made the car noticablely smoother through the rev band and powergains and increase of 4-5 PSI over stock were were felt/seen immediately. Gas mileage improved 2 mpg over my stock setup. I highly recommend this economical tune for 2006 wrx using stock turbo. Much cheaper than a protune.
