That would have been at Seattle which right now-6:00 CST at my house, is at 823 FT. Vegas right now is 3881. Just like when you go to Denver, it's too rich. It is still too rich above 3000 RPM, it just clears up to make it more drivable at higher rpm. Phone Peter, tell him you want to lean it 3 numbers or 5% from 4000 down to idle. If it still feels funny, go down 1 number at a time until it runs the way it should. Just think of 1 number on the Laptop (up or down) as 1 jet size in your carb. Let me know if I can help, or find you help. J.R. Haddad.

Thanks JR. Peter said he's never tuned the car and has never changed it and he doesn't know how. As I type this I'm setting in the car in the trailer and trying to get laptop to read the box. No luck yet.
