Setting TPS for elevation...

Okay, I am trying to solve the problem of very bad MPG in my car, I think the TPS is set incorrectly. Since I live up in Colorado at 5100 feet and race up at 6000 feet, what would be a good setting, in volts, for my TPS? Thanks in advance!

elevation shouldn't really matter on a fuel injected car. that's what the maf is there for. set it to stock.
