He knows his stuff. I just sold a 25 caliber gauntlet that I tuned using his techniques and it is a performer. The one thing I did not order was the power tune kit to be able to adjust the hammer spring. You wont be disappointed. 

i believe Haj has a couple of videos detailing what exactly he did to enhance the gauntlets performance. check them out , it should answer any questions you might have. i hear he has been building quite a rep lately with those guns.
