Just finished up tuning an 07 STI Limited. The results are pretty good. I think that I could have seen a little more torque if I would have had more time on the dyno.
The only parts installed on the car are a drop-in filter, Maddad V2 turboback and tuning. The ecu was tuned using all Open Source products. This make us the first to tune the stock ecu on an 07 using Open Source products. Thanks to all the people at Enginuity,Ecuedit and Ecuflash.
The car based at 240whp and 240wtq.
The final numbers are 300whp and 306wtq.
This was at 18psi tapering to 15psi.
