Tuning Question
If you dial in your VE table say at sea level and then move to some where like Denver. Do you have to redial in your VE table or should it be the same? I would think that a given motor will move a given amount of air no matter the location due to atmosperic pressure. At least thats what the left side of my brain is telling the right.

For the most part it's still pretty close. I travel from high to low elevation fairly often and I'm running a SD semi open loop tune with CO3. The computer seems to over compensate a little though. When I go from high elevation to low it gets a bit rich, and when I go from low elevation to high it's a bit lean. Should be the other way around it if wasn't compensating. It's not much but I tweak it back right anyway.
Anther thing, it you tune at high elevation and then go to low elevation, your going to get in the areas of the VE table that you couldn't at high elevation cuz the air is more dense at sea-level.
