Procircuit T4 jetting question

Has anyone had to rejet their 2000 or 2001 for optimal performance for the Procircuit T4 header & exhaust? If so, what specs & for what elevation/state.

I was wondering the same thing, my 00 426 seems to run ok with a 165 main, 45 slow, and 1 3/4 turn out. I have the 2" I.D. endcap and 1000' elevation.. was interested in anybody who tryed other settings. thanks mike
