Tune is the same as it has been for years and no new parts have been added. Battery is tied down securely in the trunk with no possibility of arcing. Plugs are new and gapped to the same .19 they have been since the tune.

If I accelerate slowly, meaning no boost, I can get the car all the way up to redline. If I boost at all, even 10 lbs, as soon as I get around 5500 rpms the car will buck and jerk.

I swapped in some different plug wires and a coil pack to see if that would change anything and it did not.
