Ok its 01 c5 with 10psi procharger and 60lb inj. I have the VE and maf tables dialed within +/- 2%(using a WB). Everything looks great when im in open loop but as soon as it kicks in to closed loop it goes to hell. Bank one sensor 1 reads like 600 ish Mv. Bank two sensor 1 drops down to like 25-100 Mv throwing the fuel trims way off. When i am in open loop they both read withing 50-75 Mv of each other.I have replaced the O2s checked the wire harness just about everything i can think of. any help would be so much appriciated
