Thread: tuning help please

I have an e-manage blue and I recently replaced my motor and turbo. I had the e-manage before and when I would add more fuel in the injector map 1% or 2% I would see a difference in the wide band A/F's. However, now it is taking about 70% or 80% to even get it to richen up. It also goes lean between 2,000 and 2,400 rpm under part throttle for no reason. I don't know if there is a bad ground for the injectors I checked all the connections and they seemed good.
I'm just not sure what I should try to figure this out.
