not logging short term fuel b1 & b2 right

2001 GT
4.6 2V IP Heads Stock
Stock bottom
Comp Cam II 270/550 Stuck straight up
5.25 crank pulley
3.33 blower pulley
V1 T-Trim blower
78 BBK Throttle body
PMAS Slot style MAF
60 lb injectors
Intercooler 31"x12"
Champions gapped at 30

PRP shows counts and #mass/tic and Livelink shows as counts and #mass/min

Short term fuel reads as 1.0 or maybe .99 or .98 even when wideband is showing 22 at anything just off of idle. At idle wideband reads 12.8-13.5. I'm trying to log idle 1500-2000, and 2500 rpm to see the short term fuel use to calculate and then make adjustments in MAF Transfer Function. But anything off of idle goes crazy, can't maintain rpm steadily for accurate logging. And my mass air reading goes from 2. at idle jumping to 200-300 at around 2000 something. Idle rpm set at 950. Could part of it be that I'm below stall with 3.33?

I will try attachments
