However I read one company that is famous for their "Deletes and hardware " and their Chief engineer made a great point. He said they would be able to get 40% more power out of the new Duramax's but the problem will be that the Allison transmission clutches won't take that extra power so you will end up with a fried $5000 + transmission unless you redo that from the beginning. I say leave alone. I customize my motorcycles and do it myself. My truck is staying the way GM made it. Guess I"m getting old. LOL
And in my opinion if the Allison won't hold up to that kind of increase in power the Asian & whatever Ford uses don't have a prayer, that Allison is damn near bullet proof.
To add to the fuel comments, what about the ethanol blended gasoline?
That was never intended to save fuel as when mixed 10% you can almost count on a 10% reduction in fuel mileage + about that in performance. That was, not trying to offend any farmers on here, just another market for corn crops. Did absolutely nothing to lessen the dependence on fossil fuels, which is good for me as I'm 3rd generation that earned a living from the oilfield.
