im looking for some opinions on settings. highest egt's ect. i have a 2003 2500 with a hx40 tst/ex and 5"exhaust. thanks

Set your max EGTs to 1250 on the street.. Max it out on the race track.. 1250*F is the melting point of your piston rings, but you can run over 1250 for up to about 20 seconds before damage occurs..
