Broke my car

[WC_Racer]

Kinda. I was coming back from getting my car tuned and while on the free way (please read the rules again). I downshifted from 5th to 4th and next thing I know the car starts to jerk. I figured I just ran out of gas since I've been driving for a while and because of the 4 dyno pulls. Well I got off the freeway in time and let her rest while I went to get gas. Well she was full and she would not stay while I cranked her. So end result I had to tow her home. Anybody have any ideas what it could be? Someone told me I could have a huge vaccum leak or I blew some of the intercooling pipes out and messed up the MAF. Or the fuel pumps just crapped on me.

Set up is a P1SC with an intercooler with 42lbs injectors with a BA2800 running twin focus pumps.
