Idling problem

[vtv6]

Hey guys can't find out the problem with my new engine hoping someone on here could shed some light.
when it idles it is a bit rough it has a comp stage 2 cam in it so I would imagine that would have something to do with it but it goes up and down a little bit in the revs and when you goto drive it stalls when you come into a corner or take your foot of the accelerator to slow down the revs drop fast and stalls, I have pinned the throttle cable open with that black clamp on the cable near the TB and it idles just under 1500rpm and it drives like it should until I stop the car and start it up again I have to unpin the cable and pin it back again. Thinking about getting a custom kalmaker tune because the mechanic said it seams like the ECU is not getting a return signal from the TPS or something

Thanks Guys

thats your computer not coping with the cam, i know of somone with a supercharged 6 and it does the same. you need a tune.

I got Steve from MACE to do me a memcal for the cam though.... could it be a bad tune and just need to send it back to MACE or would I be better off getting a Kalmaker tune
