Default Letting off brake/idle rolling car wants to die

Using HPTuners here.. LQ4 with a 4L80E.. With a cam

Whenever I let off the brake in drive or reverse and start rolling under idle power, the engine bogs down and wants to die. Once I give it throttle it runs great. It idles great In gear or In neutral whenever I am at 0MPH. Once I start moving the idle drops down to 500-600rpm and wants to die. Commanded idle speed is 800rpm. 950 rpm with AC on, but it doesn't even try to stay 950rpm once I start rolling..

I've messed with the base idle air table,but this still happens no matter how much air I add

What tables should I mess with to correct this?

I solved the issue by setting Throttle Cracker Enable/Disable speed to 20mph (was 2MPH originally). I'm sure this isn't the best way, but it worked.
