P0016 code and horrible fuel economy

Ive been trying to figure out my fuel economy issue when i have time. With the dsp 5 switch on the mpg tune im getting about 12mpg and thats been the best but the others are close.

The truck does have the code p0016 crankshaft and camshaft correlation. Would this cause bad fuel economy?

2005 GMC 2500HD 4x4 4 door short bed. Spur of the moment auction buy

1992 GMC 2500 6.5L Turbo Diesel 4L80E transmission. Best truck ever.
