Well my "miss" is getting worse. The car is strong from idle to 4,000; after that it feels like tons of timing is getting pulled. ANd this only happens at WOT. If I back off the throttle a little and run it all the way up, she pulls hard all the way through. WTF?

I hooked EFILive to it, so I have data on the 02 sensors, TPS, Advance, and rpms....
