Talking Exhuast Leak Maybe? :-D

Well, in the quest for more power I'm evaluating potential area's that need improvement.

Such being, I think that three things that could be causing my high rpm bog down...

Note: When I watch my SAFC it jumps from 48%to 60% Air Flow during the bog back and fourth, the rest of the way through the range it's at about 48%...leading me to think that the first option is the culprit!
  • Plugged Up Exhaust
  • Not Enough Fuel
  • Bad Spark

I think I eliminated the latter because I took all the spark plugs out and basically scrubbed the crap out of them, the plugs still looks good.

Fuel delivery could be an issue such as that the Fuel Filter probably has never been changed.

But the main reason I'm thinking exhaust is because it'll jump up to 60% air between those two bumps in the high rpm range (7,000 to 8,000 RPM).

Any suggestions? Oh...just to show you the state that my exhaust is in!

I totally spaced, but after that hard run we should've looked under the car, I gaurantee that cat was probably glowing red!
