Spartan 210 Shifting with tow/haul on

I have been loving towing with my spartan on the 210 normal.

The 210 tow is too hard a shift for me.

My question is, is it normal for the truck to defuel on the 2-3 and 3-4 shift while in tow haul? It is almost as if I am lifting my foot when it shifts.

I am not sure if it is good or bad for the truck. It seems to cut fuel to shift and then eases the fuel back into it when its in gear.

I haven't heard of that happening. The shifts do have a slight "defuel" with the 210 and under tunes anyway, but its nothing major. I have never noticed it being any different with tow/haul engaged.
