04 ss 3.8sc have been driving fine with solid security light for almost 2 years. have installed cold air inductions intake, then zzp headers and catback got p0170 lean bank 1.

so i decided to put the zzp tune on it. bought hp tuners, download stock tune sent it to zzp, got modified tune back, would not complete upload. multiple attempts later hp tuners timed out every time. decided to replace ecu

bought reman ecu installed and was able to successfully upload vin file. car started and had little rough idle then i notice 0 oil pressure. figured i need to upload tune. uploaded stock tune, said complete, now nothing when i turn key

got security, traction control, service vehicle in message center and fuel pump constantly runs now
