I just installed a TFS intake and a 70 mm tb on my speed density car. When I start the car it runs really rich, has a rough idle, and if you put you hand on the intake every once in a while you can feel a pop. the timing is at 13 deg. Do I have to switch to mass air, or is there another fix?

What fuel pressure and timing are you running, what cam?

You need to change your mass air.
