Well... after car sat all night, pressure read 10psi on start up (after setting it to 6psi yesterday). Then drove around the block a couple times and it came down to 7psi... drove ~15miles to the track and read 2psi ... so it seems heat is the culprit. Does it make sense a regulator would do this? For now I'm stuck with it and will try to set it so it runs ~4psi when hot and try to keep from flooding out when it's cold... then time to get a better regulator...

Anyone hear of this happening?

Thanks,
