Default black smoke

i got a 11.1 6.0 with a ported TB and the TSP TV2 112 with svo 30s

now my problem is when i first go WOT i get a rich cloud out the pipes. i have a LM1 wide band with a LC1 gauge. my target A/F is 13.1 now i see an average of 13.0 when at WOT. the cloud is worse in 1st and 2nd then it is in 3rd. anytime i go WOT i get this cloud. now its not as bad as it was when the A/F was around 11.9

now what could this be, ive tried several different tunes and all get teh same results

any help would be appreciated

I have the same problem with the 30# SVO injectors (2 different sets) and wide band. I run 12.5:1 A/F and mine smokes like a freight train at WOT.
The problem has continued through 2 different sets of heads, LS1 intake, 2 LS6 intakes, and a FAST 90mm and two different sets of headers

Yep...I do not know how to fix the problem. I might try a different PCM.
