Recently installed cams and heads. On Dyno no issues. On street when I floor it the car hesitate for a few seconds then takes off. When I brake torque it,It will just sit there till I let off pedal and slowly apply pedal again then the car starts to react.I dont know if its vacuum, throttle issue,or do I need a bigger fuel pump? Any help would be appreciated.

 

Is your traction control system on or off?

Try it off to see if it is the problem.
