So I had my car tuned by NPG and datalogged it and sent him that so he can adjust it. I don't know anything about tuning but when I was looking at the datalog I noticed that my injector pulse width in banks 1 and 2 were always pretty close. But when I did a WOT pull in second gear, at 6172.75 RPM's bank 2 width is at 2468 and bank 1 drops to 1100 and continues to drop all the way to redline while bank 2 stays consistent. (ex. 6234RPM WOT bank 2=2534 bank 1=410, 6393RPM WOT bank 2=2422 bank 1=286) What does this mean?

Also, I started the second gear pull from 2000 RPM's and when I opened to WOT my spark dropped to 8* I am assuming this is to prevent pre-detonation when you are at WOT in the lower RPM's?

Thanks guys
