Any fix as to why it was throwing a lot of fuel at one bank? Mine is doing the same thing. I replaced the o2 sensor and it was great for a day, and now it is throwing 25% fuel at the drivers side so it starts to run like trash. I guess I could limit the closed loop stft correction to 5%, or just leave it in open loop like I've been doing. I think it has a slight leak from the primary but nothing that bad. The location on the collector is less than optimal, and its at 9 o'clock.

I think the tuning guide mentioned that it was challenging to tune large turbo cars because the maf counts will flatline even though the car will continue to make power, so it will start to go lean. And you had to use the fuel multipliers or the base fuel table to get more fuel.
