I have asked him about this with a datalog, but only said it might be timing. he said this happens to alot of built FA20 motors. But I know i timed this motor correctly. No further info on his end about my issues.
I'd love to ask another tuner about this. I keep thinking it's the tune or ecu.

Well, we all know that Zach knows these cars like the back of his hand. He did my flex-fuel tune and I found him very easy to work with. I was able to get some custom programming out of him with my setup by having him write four different power levels on the four maps.
So, I was wondering if all of your sensors are OEM or do you have any aftermarket sensors installed that could be at fault?
And......
What happens when you disconnect the upstream O2 sensor and try to start with that disconnected?
