I was looking into installing a Innovate DLG-1 https://www.summitracing.com/parts/inn-3891/overview/ I looked it up on you tube and found the a video where they installed it in the rear o2 bungs behind the hiflow cats on a 16 Camaro SS with LT headers. Thought that would be convenient. Then I read the instructions for the gauge and it said not to install after the cats as it will skew the reading lean. Iv seen tuners tune with the o2 in the exhaust tip. Is having the o2s installed after the high flow cats ok? https://www.youtube.com/watch?v=UcXNO-SrjXI
