throttle body spacers: worth the money?

[southern_chevy]

ive got a 95 with a 350 and i was thinking of getting the airaid helix (i think its helix) TBI spacer from summit. I was wondering if TBI spacers really have worthwhile performance gain and if its worth the 90 bucks.

I have that same spacer , and I personally could'nt get over the difference it made , lots a torque , and it does'nt downshift as much on the highway , I think its well worth it .
Spacers seem to really work best on these TBI engines .

alright, the people at summit told me that they doubted if it would give any power to my truck but i have also had a lot of friends tell me it works pretty well. how bad is the whistling sound?

[MATTMC]

I have no whistling sound , just make sure your fuel lines are not rubbing against the body , because they will transmit a ticking noise , which is actually the injectors pulsing .

I put one on my old 94 a few years ago. Highly recomend it. :10: I could tell a differencr as soon as I stepped on the throttle. Slight fuel milage increase, too. No whistle either.

Have you ever heard of CFM-TECH? I think that they have a better TBI spacer from the reading I've done.

I installed an airaid spacer on my 91. Best mod I've done to the truck so far. Right away I noticed a increase in throttle response, and low end punch. No whisle, easy to install. One thing you will have to do is adjust your TV cable of you have the 700R4 tranny.

One Good thing about having a 1993 or newer truck is , you don't have to worry about the TV cable .
