[QUOTE="IHPowerstroke7.3, post: 1377483, member: 7642"] The 6.7's have been detuned in the 550's and not certain but I believe the 450's were using the same tuning as the 550's pre 2015. Detuned compared to the 250/350. Edit: Beat me to it. I'll add that I also agree that is not wise to run any vehicle at its maximum capacity and expect it to last. I work as a diesel tech for a dealer. A customer with a 350 6.0 was trading in his work truck for a 150 ecoboost. Knowing what the customer hauled regularly (a tri-axle dump box trailer) I advised it would be better to step up to at least a 250. Customer said "well it says here in the brochure it can tow it!" I said yea, it can, but how many times and for how long? A truck is like a tool, if it's something you're going to use everyday why get a tool that is going to be running on edge every time it's used? As far as I'm concerned however this truck has an underlying issue. Why did it make it 100k on the stock engine and now all the sudden start cracking Pistons? [/QUOTE]
