STFT at 40+ I have a 2007 L92 with a small cam. 218/230 .600 lift with 114 LSA. LS3 intake/injectors. Card style LS3/LS7 MAF. E38/T42 with 2007 truck OS. Just got the car running. It starts, runs rough a couple seconds and smooths out. STFT are at 40+ when it smooths out. O2 narrow band cycling. Drove around block. STFT still at 40+. Drives fine. No codes. Fuel pressure at engine 58 psi at idle.
I am using efi live and changed injector settings to match 2007 corvette. Change MAF to PowerMaf 100 table (from Lingenfelter site).
Is the STFT at 40+ expected since I have not adjusted stock tune yet?
Or do I need to be looking for another problem?

Yes, what is Power MAF 100? Is it a new MAF or setting to plug into a tuning suite? If I was you I would recalibrate the MAF then work on the VE table provided you have a wideband.

I should have said powerMAF tables (http://www.powrmax.com/PowrMAF100%20Tables.html).
I will start by adjusting VE tables with wide band. I was just wondering if the stft would be expected to be 40+ with stock tune or if I should be looking for other issues. Noob question most likely.
Thanks
