2010 mustang gt has Hotrod cams, jlt series3 intake, Barton short throw shifter, and Brenspeed tuning. My issue is under acceleration I can feel the clutch pedal move towards the floor as if it looses pressure have pretty much no clutch but will quickly return after letting off the gas for a moment then act normal. I have changed the master clutch cylinder which made an improvement, there is no clutch slippage at all. Any help would be appreciated thks.
