cam and heads, now i cant get it to idle. help i installed LT headers, heads and cam the cam is a cc503,
Now the only thing i cant get this thing to do is idle if i keep my foot on the gas just a little bit i seems like a good idle but i cant figure out how to keep it like that adjusted the fuel pressure because i got a new aeromotive one it about 40 psi right now but i went up and down to see if it would change no luck,
the only thing i can think of is that my tune is for a CC306 cam but everything eles is the same could that be it?

I'm not real up on the cam model/numbers yet, but is that cam considered a fairly big cam? Have you tried adjusting the idle via the throttle body? I know the stock one has an allen screw that allows you to bump open the throttle plates a hair more at a time. If the cam is pretty large, you could be running low on vacuum and it would cause the issue you'e seeing. Have you tested vacuum? Have a gauge to do so? Test it while bumping the throttle up around 1200-1500 and see where it's at.
