I believe the 13 Matt is referring to was my truck, which runs like a top. You have to have both EGR Harnesses unplugged. So Grand and I both had issues with how the trucks performed without those harnesses undone. Both of us and Rudy both have had our 13' Platinum's tuned for a while now, and I think mine runs better than my tuned 11 did hands down.
It does have a different exhaust sound, veins sweep a lot less than my 11 & 12 did, thats for sure. My 12 would sit there and cycle ever 10-15 seconds at idle all the time, even more frequently when it was warmer weather.
Also, if you do not have an EGT sensor hooked up, make sure you turn off your defuels, mine was reducing my truck to stock power all the time because the active defueling was on. Shut that down, runs like a champ, put over 2500 miles on it since I deleted 2 weeks ago
Hopefully this helps some
