mine has been doing it ever since i can remember.mines a standard and my dads a standard too.try a diferent tune or even a stacker tune.i know the stacker tunes dont raise rail pres but one of them may suit ur truck beter.i run the rkl with no timming added.i dont notice the rattle near as much if any with this tune.i use my x2 for timming and i can turn it off or on on the fly so i dont run it in the colder months.try some dif tunes though it may help u.
