Fitting in several Tmax values

I found the huge CHI-SQ in super-layer 1 and section 3. To fix this, I had fitting in several Tmax values. I can not remove the huge CHI-SQ even though I use any Tmax values.
Tmax 150, CHI-SQ(S3SL1) 13.41 Tmax 160, CHI-SQ(S3SL1) 12.52 Tmax 170, CHI-SQ(S3SL1) 11.01
Tmax 180, CHI-SQ(S3SL1) 11.35 Tmax 190, CHI-SQ(S3SL1) 11.03 Tmax 200, CHI-SQ(S3SL1) 10.69 Tmax 210, CHI-SQ(S3SL1) 10.08
