TDC is the real thing / Jon knows Subaru's and he has tuned so many of our cars with different mods that when he does a street tune he matches your mods with a proven dyno map - then tweaks on the road.

Also as he tunes he asks several questions about your driving style and informs you what changes he is doing as he tunes. Truly a custom tune!

Jeff - can you make this thread a sticky as I see with another tuner
