well im new here and to the focus family. i bought a svtf about 2 weeks ago. the car seem sluggish and not powerful at all. so after doing alot of research and alot of reading i did a full tune up on my car. i did pcv, fix the leaking vct, fuel filter, royal purple all around, copper plugs, k&n drop in, clutch pedal sensor, shifter counter weight removal(didnt like to much so put it back), heatshields out, and a nx wet kit(75 shot). i have to tell you the car is a different beast now. "ITS ALIVE" lol, anyways. the nitrous is fun as it is always. still have some of the bogging issues but ill take care of that with a tune soon i hope. so all around the work i did today went ok and had some good results.
