Help with tune

[hajm55]

I have a 2000 silverado 5.3 turbo, i am trying to race it in sd ol only.
It should be mentioned that i am new and i do not plan on having my tune made on the contrary i want to learn sorry for clarifying this but then they come and tell me to take it to a shop because i am not going to get free work here (they have told me before).
I purchased a course but this is not very focused on my needs, i have managed to correct the idle a little in drive and park only now i am a little lost i just need someone to guide me where to continue or where to continue correcting if it is not too much of a bother.

Hardware specs:
-ebay turbo (just to test since it is my first project, if it works as desired i will buy a brand one).
-hotpart headers (single turbo)
-cam upgrade
intake exaust
*duration .50 212 218
*lobe lift .353 .353
*valve lift 1.7 .600 .600
*lobe separation 114
*intake center line 111

-stock bottom end
i already did the 2 bar os upgrade

I don't have a ton of help to give, but first:

What injectors?
What fuel pressure?
What type of regulator system?
Do you have a Wide Band O2?

Make MAF Fail Frequency 0hz not 50. Disable Trans Diag>Max Line Pressure DTC's.

Normally I'd say throw the decaps in the trash for some Deka's, but you're only sending it down the track.

Looks like tuning with a faulty MAP sensor is how the VE table got massacred.

With the 2bar OS you have to be logging the 2bar MAP sensor PID and remove the SAE one that's there right now.
