I was playing around with BorgWarner MatchBot program for a bit.
It has a lot of neet info in it for making a turbo choice, you can relate it
to other turbo manufactures. What becomes quite prevalent is the amount
of air you need at high altitudes if you are running a efficient intercooler.
The efr 6258 has close to the same map as the garrette 2871 but with a higher pressure ratio
The two maps are at 2500 and 10000 feet on a turbo nytro running 18psi of boost, around the 300hp mark
2500 feet
10000 feet
The link is for the online program
