Signle Turbo 4.8 Rich Idel, Help Please

[mitchmxz]

Hello Everyone

I have a 2004 Sierra 4.8 with a single 67/62.

Motor is stock. 450 fuel pump. Referenced regulator set to 58 psi and 100 Lbs alpha injection injectors with 8AN feed to after market rails. MAF delete with RIFE IAT.

It is supper fat at idle and I'm not sure what to be looking for. I tuned the min palace way down and took a LOT out of the VE at idel and the idle log still shows about 2ms place with.

This is my first turbo tune so it may be a bit crude, If I miss anything you may need let me know.

I also attached a longer log.

Thank you in advance for the help
