Might had something under the hood. Also, you may want to get a scanner to see if you have some KR. Overall, racing has a lot of factors. Power/weight ratio can make a difference. Were you at a light or on a H/W?

Hello,
Around 30K, I noticed a loss in power and gained it back after changing the plugs.
I also experienced corrosion on my coil pack terminals, which robbed me of a few tenths, and destroyed my stock wires.
Just a couple of things to consider.
Later now,
Clint

I know I have a PCM issue- the previous owner had a flashed PCM installed and then put the stock PCM back in, problem is- the stock PCM is shitting out and doesnt like going over about 4300rpm.

Hello, What gives you the idea that it's the PCM? With your mods, the stock PCM shouldn't give you problems on the street.... If you have a smaller pulley, you may experience problems at 100+MPH.

I got my OBD2 read today at advance AND at my buddy's house. I guess problem wasnt PCM. Turns out O2 sensors have gone bad. So thats an easy 140$ ouch. If I install these and they dont solve the problems, I still have two new O2 sensors, but Im down 140$. Any other ideas before I go down to Advance tomorrow and lay down some cash? A new PCM is like 150 online.

Plugs and wires, plugs and wires, plugs and wires......
If you haven't already done so, this would be the best place to start..... The OEM plugs and wires are a great combination, but they don't last forever. I had to change mine at 30K.
Wires will last a lot longer, as long as your terminals are shiny. Any corrosion will destroy the wires.
Later now,
Clint

Im picking up the o2 sensors after work today, and installing them as soon as my exhaust can get a chance to cool down, hopefully not too long. Im only getting ~15.7 mpg, do you guys feel as though the o2 sensors will also help my gas mileage by a little bit? any advice as to what else to change, how hard are the plugs to do?

The front O2 sensor and back plugs will be a PITA. Rotate the engine forward. It'll help.
