Carbd Procharger Part throttle lean problems

[Supervette]

The car cruises around town with light load fine, and runs great at wide open throttle but when you start to roll on the throttle and give the car more load in between light load, and WOT, the innovate wideband starts to show it going lean? This starts happening around 20 percent on up. Background information of the engine is that its a 383 chevy with a D1sc and CSU built carb w/ solid roller cam, single plane intake, running e85 with no intercooler, and a manual transmission. This carb has the 50cc acc pump kit with the big brown cams in the second hole. It came with the green ones in place but I had lean pops and the accelerator pump cam swap enabled me to fatten it up a little more but im still hitting lean AFR a little further up the transition to WOT. It also seems to read differently when im cruising around town. Sometimes at the same position of throttle at different times I will have leaner moments than others. Is my carb pump being drained?? It seems to reset itself kind of when I let off the throttle for a bit. Since my pump cams are maxed out Im wondering if this has to do with the shooters in the carb? I believe this is my transition circuit in the carb that is causing this. How do I fatten this up?

Any ideas to help me tune my way out of this????

Thanks in advance Mike
