compensating for altitude

["Frank Amoroso" <FAmoroso@svbank.com>]

Ok, so what are the percentages for turbo audis? For instance a stock S4 in 
let's say Boulder, CO how much of the stock 227 bhp is left at approx. 5,350 
feet? The EC article mentioned force fed engines only very briefly.

What do I need to multiply the bhp readings on my gtechpro by to get sea 
level adjusted bhp on a turbo vehicle? Anyone?
