What is eveyone idea on using a throttlebody spacer for more hp and fuel mileage?
Has any one heard ne news on the "twister" fuel saver? I have heard it is junk but some say it works. CAN ANYONE TELL me their opinon?

 

They're trash....I've never heard of one person actually gaining anything by installing one. And I have yet to see any dyno numbers that weren't from a company that manufactures them that actually prove they add HP. The only thing they're good for (in my opinion) is for a place to install NOS nozzles.

 

dont forget the paper weight use... and or door stop...

 

I don't know what all you are talking about. i put on in my 2001 on top of the 360 and got a 100 hp boost out of it.... oh wait that was the nos... NEVERMIND!!!!!

 

screw the spacer, just get a new tb
