For some reason on cold & warm starts pcm is pulling timing and killing engine unless I give it a little throttle I have looked over everything in the tune and cant find the problem I am new to tuning, I am sure its something simple, So if someone could please review the log & tune & advise me what's happening that would be much appreciated..
