DE-CAT Lambda Problem

[RyanBurrows19]

Hi recently gone de-cat with raceland manifold, it has one lambda hold under the sump where it meets/connects to the rest of the exhaust i have pluged the first lambda wire into the lambda that came with the mainfold i have a engine mangement light and it seems to be down on power, and i belive my ECU is limiting the power becasue when you put your foot down its almost like turbo-lap nothing then all the power comes at once

Please Help

Probably connected the wrong lambda sensor? Like you plugged the oxygen/02 sensor and left the fuelling one out?

think ones gotta be plugged into mani another into a sleeve so that you get a clean air reading
