Still that is a pretty flat torque curve to start with.

Yes it's very flat. The Tacoma is a slow turning low end torque industrial engine. The redline is only 5,600 rpm and there isn't much over 4,000 rpm.

The dyno charts don't show it but the truck pulls like a tractor right from idle and even below. I measured the slope of my driveway with an inclinometer and it's 12 degrees. My fully loaded truck climbs right up it even down to only 500 rpm without stalling. It vibrates just like a tractor engine. If you've ever driven a tractor, you'll know exactly what I'm talking about. I live and work in a steep canyon and am always crawling up and down the hills in first gear, so this spacer exactly suits my own needs.

Here's the dyno run with the tooter spacer. All the sound is the intake because the exhaust was stock when I ran it.

And an acceleration run, same spacer, stock exhaust.
