I'll have to admit I'm somewhat of a purist. It seems every time I've tried freeing up a few extra horsepower (intake set up, exhaust work, etc) I have always wound up regretting it for the headache it took to make it work, or the headache afterwards from how it subtracted from another aspect of my ride.

I don't mind mods, but for the most part they're not for me. If I want more power of my truck, I'll swap the engine for something that has more power and is more fuel efficient stock, which is why I'm planning to put a Cummins 4BT repower
