Well I have no way of scanning for KR anyway. The car had been run with just a 3.5" pulley and whatever tune it had before I bought it since before 2008 (I picked it up in november or 2011). So technically it should be safer than before or do headers need tuned in?

Yeah running open headers is really loud. lol

Isn't there something called a torque app out there? Can it be downloaded onto Ipods and such? How does it work?
