Not trying to hijack the thread, but my Dad has a 12 Lariat with basic ****** intake exhaust and spar+an 120 horsepower file, he has almost 185,000 miles and he beats the living $h!t out of it everyday and his maintenance isn’t the best, oil around 10-11K miles and fuel filters every 15k miles. He has been tuned since around 88k miles so he has been fortunate I guess, he should be a testament on how tough the 6.7’s are.
