I am a new resident to the Portland Oregon area. I have a 99' Mustang GT, supercharged. The car was a fairly new purchase and it ran well , but not perfect. I looked for a decent performance shop in the area that was fair and most importantly GOOD.
I found (PRE) Performance Race Engineering. Located minutes from downtown Portland, they are in a convenient location and are great at what they do. They mainly focus on imports, WRX's being their poster child. However they were welcoming to my american made stang and got to work quickly and professionally to make my GT perfect.
They knew i was on a budget but gave me straight answers, showed me the problem in person, and got me on my way. I got 42lb injectors put on, new programmer and tune, and a new blow through set up. Runs and sounds excellent now.

I HIGHLY recommend PRE for your performance needs in the north west Oregon and south west Washington area!
