Well my buddy has a 87 non turbo. And at around 4000rpms his fuel cuts off. That is if he gets on it. I was just wondering what could it be. Mabe his secondar injectors are not grounded or what? Any feed backs will help. https://www.nopistons.com/forums/pub...DIR#>/wink.png Thanks

list of modifications would help..

there is no fuel cut in an N/A... his secondary injectors probably are not opening. try regrounding them at the ecu.

The plug may not be on the injector all the way, or could always be a vac leak.
