Idle fixed (simply a poor base file) and I had Andrew Borodin remote tune it ultimately (Holley Dominator EFI) whom I have known for a long time thru LS swapped RX-7's. He did a great job and cleaned up a bunch of things... we adjusted the IAC with the throttle stop screw a few times, apparently the vacuum signal my adjustable FPR is poor (so it can't do fuel compensation), the PWM that controls my efan isn't working (wired up fine... maybe a dead unit as it is used), but otherwise seems in good working order engine wise.
If you want to get remote tuned for Holley EFI Andrew is very talented and actually has a PHd as well! Smart guy and knows does tuning 100% for a living:
