For the MAF just make sure #1 you are using the right injector value file and then fix the maf transfer function using the stft in closed loop and wideband in open loop. Get it to 1.00 in closed, get it to match what the base table says in open loop (use lambda instead of afr, it makes everything 10,000x easier). You may have to adjust the TP open loop table in open-closed loop to get it to go open loop when you want it to (.7-.8 load is a good number). Keep in mind this is all done in relative TP counts so 0 is throttle closed and about 750-800 is fully open.
Feel free to ask questions here I get bored relatively often and kind of miss tuning, been out of it for a year or so.
