Hey i just did my head and cam swap and the car will not idle on its own i have to keep my foot on the gas for it to run. I also have to give it gas just to stat it up its like a carbator car to start it up. Is this just cuz it hasnt been tuned yet but i dont know how to get it to the tunner if i cant get it to idle.

I had the same problem right after my H/C install. My car wouldnt stay idling until it got up to temp.
After the base tune, the car was fine and much more driveable. After the dyno tune, the car had the exact same feel and driveability as it did before the cam and heads.
Get a good tune and you should be all set.

TUNE TUNE TUNE! After i do a head/cam install i adjust the TB screw to make it idle
. If you have a Stock TB pull the screw out and put it in the other way so you can adjust it better
Works everytime and do not drill your blade! Make sure you put the blade back to normal or just let the tuner now that you did it so it would idle.

when I built my dads LS1 last spring, it started right up. had a map sensor code. soon as I cleared the code with my tech 2, it stalled and was hard to start. shut it off, next start up set the map code again, and again it would idle. yes, you'll need a tune for it to run ok. Im sure every setup will be a little diff. how the stock tune will react.
