Thread: Issue with injectors cutting fuel under load.

  1. #1

    Issue with injectors cutting fuel under load.

    ls9 Supercharger on ly6 with 6 speed e67 (2007 ctsv) . Drives ok under light load to higher rpms . Agressive throttle at any throttle position the injectors drop to 1% and almost stalls out. What am I missing? Setting still it revs fine with no issues. Fuel is not the issue. Had another e67 pcm (2010 colorado 5.3) with a different os and didn't have this issue . Runing the ctsv e67 due to it being a manual trans os.
