79 T/A to LS1/A4

this is set number 2 and its doing the same thing.... had it tuned at race proven motorsports in Delaware, they told me my right bank had a bad sensor, so I just replaced both of them, but still acts the same.... its a mutt of a motor, 00 block, 98 top end, heads cam, injectors, yatta yatta.... runs good at WOT but cruising it wants to bog out... has new MAF sensor, running the Vette/LS6 one, fuel pressure is good, spark plugs look good.... any suggestions?
