    stage 4 problems

    hey guys.. i just put down 300 whp on a dyno dynamics with a vf43 setup on my bugeye.. however the car doesnt idle right and i was told that its my injectors.. the car also shuts off when the rpms drop (while im trying to down shift into a lower gear when im about to stop) the car has a very hard time starting (meaning i have to keep giving it gas to keep it alive).. i do smell fuel so i was told that its my helix 660 are shot? can this be? or is maybe a seal issue?

    BOV? what EMS? Sounds like a couple different issues.. Injector scaling? possibly injectors bad (?) or just purely scaled wrong, dumping too much fuel..

    not its a utec.. stock bov.. tuned at 18 psi tapering down to around 16 by redline.. and not its protune (junior).... the car runs extremely smooth on boost but when im about to stop it begins to idle extremly low then jumps up and then back low and it shuts off...
