Helix Power Tower - TBI spacers
Has anyone installed one of these on their TBI and was it worth the money? Was there a noticable increase in HP?

It won't add that much HP, but I put one on my 93 Silverado 4x4 and I could tell a difference immediately. I had a machinist friend of mine make one out of billet alum so it's not the Helix-style, more like the Transdapt kind. Better throttle response and just overall a "crisper" feeling. I have a K&N and a Flowmaster catback on it... 165,000 and going strong!!
