Just want to explain it a little better. The 28th out of 94 placing was after the time adjustment based on the class I was running. Not sure if that's how everybody else do it though.
As for my car, the fuel filter has been replaced a few months ago, so was the fuel injector wiring harnesses. Maybe you're right about the dirty intake manifolds. I have to look into that. Those bogging really slowed me down a bit.
