Starting Hptuners

Perhaps when this was made, you could do that with whatever version of HPT was out. Likely 2.22 or 2.23.

Now with 2.24 and the beta 2.25, just doing .98 is the only way to reduce the number.

I dont think so. If you multiply a positive number with a negative number, you will get a negative number. Regardless of the HPT version number. The proper way is the multiply by less than 1 to reduce and more than 1 to add.

When calibrating my 2012 supercharged F150 That's how I did it. X1.02 to add 2% and X0.98 to remove 2%. Worked out great.

On another note. When tuning using the WB, are you guys just removing the stock NB and plugging the WB in or are you welding a new plug in for the WB? I would think for open loop pulling the NB and putting a WB in would be fine. This will be my first time tuning a vehicle that didn't have factory WB sensors.
