Turbo 3800 ColdStart Idle Issue

Hello, I've got a 96 Camaro that I did some work to, somewhere down the line it started
having some cold start idle problems, the thing will start and idle at 12ish afr when cold
but only for a few seconds then it goes super lean to the point were it will die.

so far this is what works, I can baby the pedal ever so often and it will idle but it's too lean
for what the ETC is calling for.. it will idle at 14.7 or close until it goes super lean and so forth
until the engine gets a little warm then it will idle on it's own with no input.

the other way I can do it is via the scanner and manually move the IAC to the point where it
will hold the idle and i would slowly decrease until the engine is warm and can idle without go lean

Engine is running 36lb GTP Injectors

I've added my current tune for anyone who can help with this issue
