I’ve been doing cold starts just fine, see my post immediately above for list of things that may be different from your setup to test. 
Was able to get it working from cold start, I guess I didn’t have all the updates from Content Manager. However, I still can’t get fuel switch to work, in either lock or legacy mode.
POH = “pilot operator handbook”, for most of us that have no idea what that stands for!
It actually means “Pilot’s Operating Handbook”.
I experienced the same issues, was not able to bring it above 150 KIAS, no matter which altitude I was flying.
Personal Comments:
So how do folks feel now about the performance after the WU6 official tweaks?
I’m getting very close to 180 true under 5000’. Need longer trips at different alts to see about the fuel burn.
The most I am able to get out of it is around 173 KTAS. This was properly leaned at 4k MSL and 86% power. At nearly all altitudes from 5,000 MSL to 12,000 MSL it gets 170-171 KTAS maximum. These are simply not the performance numbers of the SR22.
Well that looks right. Why in the hell am I not getting that? I can see I’m WOT and leaned for peak RPM. Tried 100deg rich of peak too.
that’s weird, the sr22 numbers posted previously are similar to mine, not sure why yours is so sluggish:
edit: maybe make sure you don’t have any mods for the sr22 or liveries and your fully updated, including in content manager.
I had to end that flight prematurely (grill duty for dinner), so I started a “Weekend Run to Bar Harbor” from Block Island. Two occupants 170 lbs (ha I wish that was me ) 130 lbs, 50 lbs baggage,100 percent fuel load.
Climbout at 125 FLC (I’m told this is close to optimal?) - no problems.
183 KTAS at 8,000, Baro 3003. Granted I have a 20 kt quartering tailwind so GS is really around 191 KTS.
Edit: 182 KTAS at 10,000.
well that settles it. something on my end. no clue what it could be, i don’t have any mods for the SR22 or anything
Moving this to resolved bugs as POH performance is confirmed following World Update 6.
