    Tori,

    I have one in my 87 and I like it. It gave me better throttle response, seemed to help with power a little, too. My friend has one in his 91 Chevy Truck also, and he swears it increased power and mileage on his (my truck's mileage is so bad that I don't see much in terms of fuel efficiency!! ha,ha) I have the old-school TD Performance spacer, so maybe that is why. The new Poweraid's are way better with their "helix" bore that spins the air...we just started selling them at work here. We also sell the Helix Power Tower, but I think the Poweraid is better.

    If you want to get one, email me at keith@autoaccessory.com and I will hook you up if you want.

    Keith

    The kit I got from Jegs, came with the spacers for the linkage. I bought the fuel line extentions and sent them back. The best thing I can tell you there is to leave the line hooked up and gentle pull on them to rebend them to fit.

    I was thinking that might be worth a shot at trying... thanks for the tip... which brand did you get from jeg's again? I remember seeing a couple different ones.

    I have one from Turbo City, but it was on the truck when I bought it, so I can't comment on its help.

    I run a trick flow, and it works great. I had to add a throttle return spring to keep the linkage from sticking.
