anyone seen one of these used before?

 

this is the TBI forum.

 

some outrageous claims there

 

oops, thought I was in TPI but they have this same thing for TBI systems, a friend used on on his vortec and supposedly saw gains in hp and mileage

 

TPI Does stand for tuned port injection, I do believe is question was related to that. Such as in a
throttle body spacer

I have a question about the same thing. I have read all the claims of horsepower and mileage benefit. Would like to know if there's someone out there that has tried it and can give some advice.

 

benefits TBI more, being a wet-flow system i bet

 

do you know of anyone that has ever used one?

by the way I like your truck, I have one similar to it than a year older. http://i120.photobucket.com/albums/o.../darktruck.jpg

 

nice, mr.gdr. I like that line that runs with the door handle. This might be apples and oranges (probably is) but the spacer (VMAX) made for the L31 vortec trucks (96-98) produces pretty good gains. I bet someone will chime in and respond, but TPI and MPFI vortec truck manifolds are pretty different.

Anyway, it's not that hard to put it on- give it a shot and see what happens. you can always take it off

 

I have a 1988 iroc, so I think I will give it a try. dont know what kind of power or mileage I have now... just fill it when it needs and race it when I need.
Thanks

 

Almost $100 for garbage?!

Put your money elsewhere. You'll be pissing it away on crap like that.

 

to late,Just ordered one. I know the ones on the Harley Davidson's work a little. I guess I'll give it a try. The price of gas that's only two fill up's. ckeck to see if I get any better mileage. Have you tried one or is it just your opinion?

 

Haven't used it. Been told by many people in the biz not to (at least not for a tpi).

Carb yes.

I just find it annoying when manufactureres put out a get-rich quick part that makes unreasonable claims in hp gians for a tpi.

 

Where I first saw it was on one of those spike TV shows about cars. Of course that was television. Thanks for your input

 

Ya, I guess some car shows will promote just about anything if advertisers dangle enough $$ in from of their eyes.

Sorry to hear you already purchased it. Well, I guess it couldn't really do any harm anyways

 

anyone tried it yet?

 

My dad ran one of these on his 2500hd and picked up about 2 or 3 mpgs, im put just a basic tbi spacer on my car but at the same time i put a fuel pressure regulator on goin from 11.5 to 13.5 psi so the add in fuel pressure kinda counteracted any mpg increase the spacer might of added
