Alright so i have the ls/vtec swap... everything was good this morning. Still pulled hard. After work my battery was dead, had to boost it ([freak]ing headlights)

Ever since then my car has no power? I cant tell if its any different in the lower rpm's because i haven't had it long, but after 4-5000 rpms it seems like there is just nothing. It still seems to rev quickly, but no power to the wheels. I can hear the VTEC at 5500 rpms, but still the car just has no go. Engine definately isnt as loud.

Now i dont know if it has anything to do with the battery dying, but i cant think of anything. I didnt build the motor and dont know all that much about the ls/vtec swap. I just figured the battery dying could have screwed up the ecu?

Fuel pressure is at 32 at idle, 40 when i give it gas....
Also it took a little while to start? Cranked for about 10 seconds then started fine... Im kinda scared to start it again right now
