What is your thread called? I want to check it out to see if thats what i have going on. Ive logged misfire on every cylinder and didnt pick up any even during a wot pull.

Not sure which thread you are asking about? The AC torque reduction will just be a sudden drop in timing when the ac clutch comes on, not a misfire. If set too aggressively (pulling too much timing), it will create a noticeable "fishbite" feel.
appreciate the link! I'm going to check it out and see if that may be my issue as well or if it's just that I can't tune VVE.
Could I get someone having this problem to either email or pm me please that wouldn't mind doing a quick test. Ran into this same problem on a genv and would like to test a theory as it seems to have fixed it. Funny thing was that it was only doing it to that one in blended mode whereas gen 4's do it only in sd mode. Never the less - dynamic air would shoot through the roof, fuel dump was occurring and timing being yanked causing bucking....
Thank you.

OK, so on the Vgen it wound up being the prediction coefficients being zeroed out that caused this issue. It was causing the dynamic airflow logic to go bonkers and freeze up the coding in the ecu for brief moments at a time... So, doesn't seem to be the issue on the 4th gens, but something to keep in mind if your having this issue and you've altered them or something related to dynamic airflow...
