Well even after installing the screen in front of the LS9 MAF, the hz reading jumped around too much (3-4 cells). My initial plan was to use the MAF and scale everything back 35% to gain g/s range.
So tonight I put my SD tune back in and it runs great, I have my WB and STFT's going and Greg B is right the NB 02's have about a swing of 3%.
I do need some help though, anytime I crank it up it idles low around 500rpms for about 3 seconds then instantly goes to around 1400rpms for about 3 seconds and then settles down to where it is suppose to, Any help on this?
Below is a log of it happening (very beginning of course), and notice the Percent difference between banks, if I can't fix this with the o2 bank Mv select I may just have to settle with Split percentages at idle.
