On my rx7 it was a 5.3l with a T70 and i put both o2's on the downpipe cause i saw a couple people do it and never got a answer on if it was good or bad. It seemed to run pretty good until it blew a charge pipe off. On this one i plan on putting them off the manifolds/ crossover and my aem wideband a little bit down the downpipe.
Daz im still in the process of gettin parts together but at the moment im using a ebay T70 on a stock 4.8l. Tripplblack has a couple more things done to his.

Sounds like I have all the answers? Is this sarcasm?
Honestly I would consider myself a novice tuner at best, I have spent a ton of time researching, learning and experimenting, added to this I have a professional tuner as a friend that's gave me a ton of adivise
With that being said I feel my tune that is a work in progress is pretty good considering, that my 4.8 w/ms3 cam holds a steady 700rpm idle and very minmal surging .
Anyways I know every set up is different but there should be minmal backpresure until boost is being made and at that point it should be in open loop, I would imagine that you have had to deal with a quite a bit of cars with improperly sized turbo causing exsessive backpressure issues .
I wonder if a o2 sensor from a lnf or other factory turbo equipped o2 would would work better in this situations , I'm sure there probably designed to work with backpressure ?
Back on topic sorry for the

no that wont work because the its going to try and trim fuel on one bank, the readings it seeing is for both banks.... i know the ford guys change there bank select in the tune so it will trim all 8 cyl on one o2 sensor... i want to try this with a ls, just have not had the chance...
