Banks products are great but what do you need it for????? you have 800 lbs of torque, SAVE YOUR MONEY as was said before the 6.7 is a BEAST
I'm going to put a tuner for my 2003 Duramax because it only has 520 lbs of torque and I just need a "little" more and My 5th is heavier than yours and I haul 2 scooters
