throttlebody spacer

[stock91]

I have a 91 S-10, and I was thinking about getting a throttle-body spacer. Does it work? does anyone have one. I have heard from some people that it does alot, and some other people say it does jack ****. Thanks.

On '96 and up it doesn't do much of anything.

On your 91 it's a worthwhile mod. Not much seat of the pants but the dyno and time slip will show it.

Something like 5-7 hp.
