STi Dyno Tuning 500whp+ Blouch 4.0xtr *Conservative Tune*

2006 STi with forged pistons and rods, everything else internally is stock. Engine work was done by FE Performance. The customer wanted a safe tune so he could hammer the car on the track with the hot and humid weather here in PR. It had more to give but we left it at 518whp & 472wtq @29psi with Q16 on the tank.
