I was reading on Summitracing.com about hypertechs programer for the 03 hemi and It said for a certain VIN number with the 8 or 10th charictar was a D, all it would do is improve the shift. Is there anything I can doto it?

Hellbilly,
Did you have this problem with your hemi? I want to make sure it will work considering its price of about 450 dollars.
