Weird WOT thing occuring.
I have been trying to fine tune my car to get the most out of it with tunercat and using Datamaster (TTS EE) to log with.
My car seems to be acting normal, Goes into WOT in second ,cell 15 is enetered, LT BLMS of course goto 128, O2s on both side read 915/932 @ 4400 rpm , Map KPA 96.7, AFGS is 228.98. Everything climbs fine here and stays pretty constant on O2 MVs drop slightly to high 800s and BLMS still at 128 up to 6800 rpm, inj dc peaks @ 73.2. Then shift to third RPMs drop to 5150 and all hell breaks loose (figuratively speaking)O2s now are at 746/906 MAP KPA 94.5,AFGS is 316.83, ST BLM for the left bank is now 134 getting worse as it climbs as is the O2 MVs , they are down to 417, it gets so bad that @ 6375 moment before where I let out (126 mph) the ST BLMs read 196/128 inj dc is 118/77.3, O2 MVs are 62/830 , AFGS is 337.10.
Car acts completely normal onthe coast down in cell 17 then settles into a slow 2200 rpm (still in third) @ cell 7 BLMs read 130/128, O2s are again moving around from 200 to 800 normally.
I checked for vacuume leaks and there doesnt appear to be any, I looked for exhaust leaks on that side and the only thing I can see leaking before the O2 sensor is slip tube on the #1 primary (hooker LTs) black soot has escped and stained around here.
Anyone have any ideas? I have all the info here if anyone wants to look it over.

swap O2s to see if the problem follows. Your problem is weird for sure. Id like to take a look at the log too if you dont mind... never have seen a WOT from a 383 with AFR heads before. Im curious how much air it flows.

Re: Weird WOT thing occuring.
Ok found out the prob, I was trying to send it past the company firewall which limited the size of files that can be sent the file is 52 mb 
I'll find some way to get them to ya.
Good news though, switching O2s around moved the trouble... Bought a new one fixed
