AFC,Maft, Keydiver Stage 3

[GSX93DSM]

I have a question. Like the topic says I have a afc,maft,keydiver stage 3. I know that the keydiver supposed to be close,so you don't have to mess with the afc that much. My question is the car hesitates just a little after 3k which means it mostly needs to be lean out. Any thoughts would help. I know I need a wideband, that is next on the list.

I try to get the chips as close as possible, but the MAFT throws a big unknown into the tune. Depending upon the diameter of your pipes and adapters, or any bends near the GM MAF, it can throw off the MAF output by 20% or more. At a minimum you need a logger to tune the MAFT, so you can see the fueltrims, but a wideband should be on your list too.
