gears and tune?

  1. 2011 - 2014 Mustang GT Tech
    Actually I have 2 questions here. My torque converter is not what I am used to? I sometimes come to a stop and when I take of quickly but not hard on the pedal seems like the stall is higher than normal? So it kind of launches instead of just rolling back out. Anyone with similar thoughts...

    2000 GT 4.6 question. We recently purchased this car. It appears the rear was changed and I am guessing by the 7mph the speedo is off, it probably now has 3.73 gears. ABS module was not communicating, and we sent it out to be fixed, which was a success. Trouble code stored in PCM for wrong...

    I bought a used 2008 Mustang GT on Saturday and it has several mods (I don't know what all has been done to it). The speedometer is 10 to 15 MPH off reading a higher speed than I'm actually going. As far as I understand, the bigger wheels (it has 20" wheels) would make the speedometer read a...
  7. 4.6L Tech
    Hey guys, this is my first time posting on a forum and I had some questions about finding a cam to put in my 2001 mustang gt. I have a Steeda CIA, BBK lt headers, BBK O/R X pipe and borla stingers. Everything else is stock. Does anyone have any suggestions on a decent size street/ strip cam that...
