    Default No response idle issue please help!

    I am tuning a 2008 silverado w/E38. It has a supercharged 408 CID built engine (stock throttle body, 227/236 cam). I've tuned about 18 E38 PCM's but have never had this problem. I've read the sticky tutorials and followed them exactally with great success on other cars. (Thanks for the tutorials!) Here's the problem. No matter what I set the tables and parameters to, the idle stays the same. I've maxed the idle airflow and went from 2% to 90% on the max idle throttle position and everywhere in between. Sorry I can't list the table numbers because I don't have my tuning computer with me right now. I can't get the TP with idle included to go over 2.2%. I'm tuning a 2010 Camaro right now and made all the same adustments and it turned out perfectly! I should also tell you that both of these vehicles are mafless. Please help!
