is it usual that the car wants to die out when you first start it up with a new cam in it? My car likes to die out for some reason (even after getting tuned). After about 15 seconds of running it idles perfectly
it might be usual if you have a bad tune.
If you have a good tune, then its not.. Issue is likely to be running airflow (desired airflow in efilive)
Can also be a few other things, like timing and some of the other startup parameters (cranking, initial enrichment etc) but more often than not its running airflow table.
