I suppose I should clarify some of the driving conditions that I face. (1) in Colorado, I drive at varying altitudes (between 4,500 ft and 10,000 ft). I believe MSII will account for the change in density of the air using internal baromiter. One of the problems I have with tuning my carb is the altitude changes when I start at 5,000 ft and drive to 10,000. What should I tune for in that situation?

Second problem I have is winter fuel, summer fuel. This is a real issue with driveability and may be related to improper tuning now? Not sure if MSII will account for the change in fuel, but I think changing my tune seasonally with MSII will be easier than carb?

Thanks for the help Stich & the gang.
