Alright: good news I figured it out! I went back through the whole timing process in the sticky. I think that forgot to click burn the first time that I did the lock timing thing. When I did it this time the idle smoothed right out. Verified timing at the crank pulley all was good. It still ran very rough though. Figured out that the timing table in this base tune is WAY low. The car likes about 23 degrees at idle the base tune had 16. Now I think that I can start real tuning. On an unrelated topic is a ve number of 50 high at idle? I tried 40 and it shut off seems to run ok at 50.

I'm not sure how you got through the timing sticky the first time without clicking burn as it never would have done what it states (commanded match actual) in the sticky but regardless, I'm glad it's working right now.
50 isn't horrible at idle, 40ish is more typical. This can be skewed by improper injector characteristic settings or errors in the required fuel settings.

Thanks Stinger! I didn't follow your sticky the first time I went off of another sites start up guide it wasn't as clear as the one on here. Could having injectors that are too small for the combo make the difference in the ve table? I'm only running 24lb injectors. Thought it would be fine as im running NA.

As long as you've set up the required fuel setting for 24lb injectors, it shouldn't be an issue (until you run out of injector). You plug in the injector size in the required fuel window.

Yeah I did all of that it all looks good. The car idles pretty good it just seems a little high. With Ford factory injectors what should the opening time be? It was set at 1.00ms

The opening time depends on the injector type (hi vs low impedence as well as which design) and how the ecu controls them (it varies with different MS systems). If you can change the squirts per cycle setting and the AFR stays the same, the opening time is correct. If it changes, opening time isn't correct.
Warm idle speed is adjusted with the throttle stop screw, not the ecu.
