bad wideband???

Hey guys today i finished up uninstalling my 35r kit and put my stock steup back on. Before i was running 11.4-11.9 WOT on my 35r kit. That was with an safc-2 and a base flash to work off of. Things i did different were obviously take the 35r off put my stock turbo setup back on, took my 780cc injectors out and put stock ones in, and took the safc out. Now im getting crazy readings from the wideband. its reading 15.0-17.0!!!!! After i let off the gas then it will read peg rich! What could be the deal? Im by no means flooring it and being hard on it due to not being tuned for stock setup again but why is this happening. The car has not saw over 4k and maybe 8 psi max. Its like the wideband is doing the exact opposite. I figured with the base map thats on the car it would run dog rich since i had the 780cc injectors in there! Someone help me out!

So let me get this straight..

You are tuned for 780cc injectors... and then you put the stock ones back in....

You didn't think you would go lean? I mean come on... bigger injectors means they would tune the cars computer to fire the injectors at smaller intervals (ie less fuel) then the stock smaller ones.....

Sounds like you need to reflash your cars base map to stock and fast.

i see what you are saying with this. But i honestly dont think my ecu was flashed in depth that much. I figured be the tuning that was done on the stock ecu which it was loaded via email, it would be dropping alot more fuel with the bigger setup i was running. What you said makes sense im not disagreeing with you at all. Im sure there are other opinions out there also!
