My mechanic in Boise swore by a throttle body spacer for my 5.0, said it was snake oil.

He let me test drive his truck with one installed and I felt a real difference in throttle response around 2500 RPM. Anyone run into a mod they were wrong about?

Ever wonder if the placebo effect works better when someone else is paying for the mod? That sharper feel @emery19 asked about could just be your brain wanting to feel the money was well spent. I've been tricked by my own expectations more than once.

You mentioned feeling it at 2500 RPM. Did that sharper response make the whole driving experience better, or was it just a small thing you noticed once?

You said you felt a real difference. Was it just that one spot at 2500, or did it change how the truck drove the rest of the time?
