Thunderstruck Pumpkin mashed too low?

Brewing Yuri's Thunderstruck right now and my mash ended up WAY too low. I put my strike temp a little low cuz I had Pumpkin going in the mash that was hot and fresh out of the oven. Ended up adding a 1/2 gallon boiling water that brought me from 150 to 154 and I let it go.

But, when draining my mash runnings I recorded a 150. I was shooting for 158.

Any good way to fix this now? I'm already getting sparge up to temp

Not much to do right now. If it finished dry, at some maltodextrin maybe?

No Malto Here.....

Anything else???

It doesn't have to be added now. Order it.
