1996 C1500 silverado 5.7l vortec engine. Running rich

I have a 96 chevy c1500. I have a new factory GM engine it seems to be
running rich. Exhaust has a strong fuel smell. All O2 sensors are new,
new cats, new MPFI system, with the exception of the EGR and MAF
sensors, all others are new (aftermarket). Here are my live data from
testerday at 66mph according to scan tool, RPMs 2052.  
STFT BK1 -0.8 to 0.8
LTFT BK 1 13.3
STFT BK 2  -0.8 TO -1.6
LTFT BK 2 14.8
MAP 15 INHG
SPK ADV 38
IAT 79 DGREES F
MAF 5.28 LB/ MIN
TPS 10.3
ECT 194
IDLE TRIMS ARE AS FOLLOWS
STFT BK 1 -1.6 TO 0.8
LTFT BK1 4.7
STFT BK 2  -1.6 TO 08
LTFT BK 1 1.6

I do have a difference of about 5 MPH BETWEEN speedometer and
what scan tool shows. Speedo showed 71mph . I believe the ECT TEMP
should show between 200 to 205 degrees for normal operating temps
for the 5.7l .. Been told these engines like AC delco parts. I may go
ahead and replace ECT with OEM. Thoughts please. No codes by the
way.
