Need help bad! Multiple problems.

first off, i have a 1986 iroc z28. with a 5.3, and a built 700r4 with 3200 stall. my problems include high idle, studders, weak on power, and dies out.

my mods include Ls6 cam, Ls2 intake, 80mm tb, custom longtubes, egr! delete, Ls1 injectors..all tuned by PCMforless.

ive tried alot of different things, just looking for another option.

-i think i have too much stall
or
-i think iac sensor is bad
or
-tranny is bad

the hardest part about this is the fact that i dont have the dash harness, for my swap, so no dtc connector....for now that is.

any advice is appreciated.

the blade is not drilled, i figured that would bring more rpm in idle...

i meant to add, the reason i think my tranny is bad is because, the studder i feel is violent...its more of a shudder and buck.

i can give those things another look, and talk to my tuner. but what about the tranny? its not electronic, just the standard analog 7004. i just feel a load on the engine, that is more than usual, and it causes most of the bucking and shudders.
