Default First Start on new build. Basic Help

Hello, I have an 05 L33 with trick flow heads, Ed Curtis Cam, LS6 Intake DBC, D1X Procharger, ID1050x injectors, long tubes, and a 4L80.

I should be set up with 2bar speed density, the correct injector data, and a basic high idle startup to fight camming over.

currently it will start up and stall a couple times but eventually start up and “idle”. If I press the gas it will seemingly misfire but then try to respond and rev up when I let off the throttle.

could somebody glance at my log and/or tune and see if there’s anything that can be done over the internet so I can get it idling and get throttle response before I wrap it up and take it to an in-person tuner?

thanks in advance!

Check to see if there is an intake leak between the MAF and the throttle body...

Which IAT did you order ?
Assume your IAT will thread in cold side pipe, near throttle body.
While you are "waiting" for standalone IAT, you CAN plug in the 5 wire MAP, and zip tie it down to the heater hoses, right rear firewall area, That'll give you SOME ambient IAT, better than the "open circuit default" which goes to about negative 38 degrees F when disconnected.
