I know this is an old thread, but i was wondering if anybody can tell what might be wrong. Above was my dyno from the last time before this dyno happened below. I only switched my injectors and went to a 2 bar SD tune.

Is your belt doing a burnout on the pulleys?

I have asters bracket setup so I'm pretty sure it can't be belt slip.

seems like its "dying" up top.

i think its either a restriction or belt slip. if the belt is old, it could have stretched and causing it to slip.

Dirty air filter? Clogged cats?

Do you have a front mount IC and are you still using the stock D-1 elbow (for the filter) or is it the truck one?

swap the filter, belt, get some good fuel from shell, and check for boost leak. also, i am assuming this is the same dyno, if you mentioned it above I did not see it.

Did you log boost? Is it dropping?
