    I'm new to tuning and need help. 5.3 Tume

    I have a 78 trans am we did a swap in. I can't get it to stay running. I'm still not sure about what changes to make. The motor is a 5.3 bored to a 5.7, It has a stock Camaro intake with 30lb injectors. It wants to idle sometimes but keeps going dead when you come to a stop. It also has a mild cam. Can someone please look at this tune and point me in the right direction? Thanks

    Add 1.5 g/sec to RAF, 2 g/sec to startup and 3 degrees to the Main and Idle spark....then tune the MAF and VE.
