Sounds like you got a pretty good idea of what you want & they sound good to me. I don't believe you have to worry about the 120race & your rods, pretty sure Bill would not sell you anything to hurt your truck. BTW that is my favorite tune period, I like the shifts & the pep. The 80dd is good but I cannot leave it there long enough to get any mileage #s, if my trailer is not hooked up I just leave the 120r on. One thing for sure is it makes the truck run really good & the throttle response is nice & smooth.
