Joseph was looking a little more from his FX so we came to his aid.  Having already done a muffler replacement and drop in air filters.  We went to work tuning it.  Since his FX is AWD, Khiem from down the street was kind enough for us to use his Dyno Dynamics Dyno.



SPECIALTYZFX50Green is the baseline pull and red was our final tuned pull.  Nice gains of 20+whp and torque and no more sudden dips.
