Elevation- loss of power/need retuned? Help So I'll try to make this as short as possible. I moved to CO from Ohio. Right before I moved I hard my car Dyno tuned, it did 350/370 at the wheels. Since getting to CO it seems "slow". Don't have any 1/4 times but it doesn't even want to break the tires loose at 10-15mph when u punch it in first. Is this just from the altitude/elevation and nothing I can do will help, or would having it retuned here help and make a difference?
If retuning at the new elevation WONT help, is there anything else i can do without going into the motor, would going to 4.10 is make big difference over 3.42's to help make up for the feeling of lost power? Dont know what else I can do since on spray i make 430/506 and Im not sure how much further I want to push the stock rods/internals

hp loss = elevation x 0.03 x hp @ sea level
not sure if thats any good.

Thanks for the help guys.
Ive been thinking about doing a motor build this winter to get to around 450rwhp and building it so I can shoot a 150 or so shot of nitrous and not have to worry about it. But I think I might do a turbo set up instead to help the altitude difference

It blows man, here these guys with bone stock ls1's go sometime high 12's low 13's and here I am with my full exhaust, ls6 manifold, SLP cold air package, dyno tune, etc…. and the best I've ever gotten my car is a 13.7 because of the elevation. It's so aggravating!
