Most of my sponsors are companies I've dealt with during the build, and they tend to provide parts and services for free. I've also had sponsors pay for entry into events etc. I'd love to think someone would throw wads of cash my way, but I think it depends on the level and type of motorsport your competing in. It's a pretty tough economic time to ask companies for cash.
It can quite easily be due to a change in resistance, possible caused by a dry solder or poor connection. This will reduce the voltage available to the cluster, which could explain the higher reading. So I'd also measure the resistance across the terminals on the cluster side, as that is the most likely candidate.
How did they get in ? Deadbolts, window locks etc are all worth while. Plus think about imobilizing the cars in other ways, like leads to the CAS or ignition harness etc

What ECU are you running ?
Personally I'd install the O2 sensor, you'll get better mileage.
Have you checked your spark plugs, chances are they're coated from running too rich.
What color smoke is it blowing ?
