Is all race gas leaded? The reason I asked is because there is a sunoco near my house that has 110octance race gas, but it says it's leaded. Is this bad? I thought someone had told me it would mess up my maf. What if I get rid of the map and go with a map-ecu or something.

The only thing leaded race gas may do is eventually burn out the O2 sensors. I've run 100 gallons through mine in the past year and all is well. You should be fine.

It won't damage your MAF.

You can get unleaded race gas up to 100 octane, anything higher is hard to find in unleaded. Lead is good for your engine, it's a lubercant! Leaded race gas wears out my bosch wideband sensor pretty quick and the stock 02 sensor after a long time.
