I did a dash cluster flash tonight. Boost was only reading 0.3 PSI on the dash. What's my problem? MAP sensor? I know someone had a similar problem recently too, but I couldn't find the thread. Thanks in advance.
 

It doesn't move at all when you get on the throttle?

Mine reads that when idling.

I can't recall. It was a combination of "I have to do some work tonight, but I really want to flash this sled and hear it run...oh why is it only reading 0.3 PSI at idle?...I'll deal with it tomorrow." So instead of doing work, I'm here on the forum of course.

I will throw the stand under it tomorrow and get into the throttle and see what it reads. I really apologize in advance if I'm just wasting peoples' time here because I don't understand how boost is measured/read.
 
As others have said that's normal, at idle mines reads 0.2-0.3. When you give it throttle the numbers should climb as you make numerically more psi of boost.
 
It has to have pressure to react,i think by just spinning the track on a stand,may barely bring up pressure. Unless you hold brake while trying to increase throttle. It does work but is only effective when track is on ground,and making hp,so even moving along at 5-10 mph dosent do much,unless you give it some for a couple of second blast,than it jumps.
 
Thanks guys. Put it on the lift, boost climbed with throttle (only ~1.2 psi @ ~5k rpm). Can't put it under load because no snow, but it sounds like all is well based on the comments here. Of course I'll be back here when the snow hits if I'm not making any boost. Much appreciated!

Sounds like you're in the ballpark.
 
With the dash flash what is the hr meter reading? Mine is zero. But haven’t watched it while riding.
