Altitude + my FD = slow
So I recently moved from Cali at a nice elevation of about 300 ft above sea level, to about 4800 ft. Back home in Cali I was easily getting .80 - .85 of boost reading on the PFC, but now I am struggling to get .60! I know that altitude will affect the spool, and boost in general since the air is thinner, but is it normal that I can't get even close to what I was getting near sea level. I did try to close the wastegate more through the PFC, but I have read about how the stock solenoids are not very good, so I don't know how well it's working. Does anyone have some insight to what I should do?

When I lived about 6000 feet in Colorado Springs I had down pipe and high flow cat. This gave me something like a 10-7-14 boost pattern. I used the home depot boost controller and pre-control to get that to something like 11-8-11.
Altitude does affect the boost control system, but you should be able to do better than .6 bar

Ok, so here is my boost pattern. Well, my mechanical boost guage reads something like 10-6-14... But the Power FC reads: .45 - .28 - .65, which is something like 6.5 - 4 - 9.4 in psi. I was able to get a peak of .76 on one pull, but I changed the wastegate % in the settings on the PFC to 82%, which is much higher than the usual 74% I have it at back in Cali.
