MAF-T tuning.

[Talon628]

My setup: 60-1 t3/t4/full exhaust.,walbro 255, AFPR 1000, PTE 680cc injectors, MAFT gen1 w/3" GM mas.

So yesterday I put in My boost gauge,water temp,and wide band o2. I went to go try, and lets say make sure i can drive it(tune). so I got it pretty good just by watching the wide band,(no I dont have a data logger cuz my obd 2 plug is broken on the car)and got it to idle stoich/rich, then got it to run the same at WOT. But the question I have is,can I adjust it for partial throttle? Because like when im only a little on the gas it will stay almost lean, only until I stomp the gas will it begin to richen out. Or if that is normal....Because I noticed the turbo would spool at partial and yet it still reads lean, and then when floored it'll read rich.

That and also, when I keep it in gear, but let off the gas it leans out? normal or odd?
