Elevation sucks. It puts the compressor into a higher PR on the map, which hurt efficiency slightly. But it makes it harder to push the limits of the turbo as well because it is harder to keep the turbo in its efficiency.
compared to high elevation at 12.6 absolute pressure.
It pushes the turbo out of efficiency to push past 500hp. 480whp on 26psi is good, but I really felt like the boost was pushing the limits of the plastic maf. Also the boost controller wouldn't allow more boost. The 6262 will make my goals much easier I think.
