I had one and had it dyno tested when I had my Unichip tuned. We got inconsistent results, and no improvements that you would ever notice. Here is a link to the dyno charts.

It seemed to help a tad down low, but did screwy stuff up at the top end. I gave mine away.

ive got one, combined with the trd cai, its not bad. i put them both on at the same time, so cant really say one works better with, or with out..on my last tacoma, when i added it, i noticed a little diff...so, i guess i just assumed it made a little diff here...

I put mine on about 2 months after I put the CAI on. there has been no power increase, the gas mileage is the same. The only thing is you can hear a whistle...

Something just occured to me...
A throttle body spacer would hurt performance by by giving the air more time to warm up before it enters the combustion chamber. We already know that there aren't any gains, but my thought was that the performance stayed the same. Now I dont think so...

I think its no big deal either way. It won't hurt much and it won't help much.
