things to note:
-absolute **** video quality makes it out a bit worse than it is
-also super loud because its off the downpipe
-good spark on all four plugs
-the engine ran excellent in the last car it was in last season.
-all emmissions removed as well as the stuff on the throttle body
-car was warmed up around 165F when video was taken
