its probably the heat soak from the IC, pretty much everyones car has been like this from the beginning

I Have Ion Fmic Though

well heat soak is not the problem then ;) sure you dont have a leak? I know some of the other guys had similar problems and their clamps were not all tight,

or maybe you have a leak in your boost lines somewhere

The boost drops because the plastic pipes expand under boost. It was most likely there before the flash but you didn't notice it.

My boost peaks at 8psi, and drops down to about 5.5 near redline, both before and after flash.
