    Default Throttle body spacer

    I got a 09 silverado with true dual exhaust kn filter and diablo reprogrammer installed, Does the throttle body make a difference? or are there any other bolt on part that I could get to help out with HP and torque?

    My friends got one on his '97 Silverado with 5.7, every time he touches the gas you can hear it whistle faintly. kind of sounds like a turbo. He said he's experienced an increase in gas mileage, and a little low end torque. Not my results but a friends.

    every tuner i have talked to said that it will make no diffrence on the nbs pickups. Jessie, Wheatley, and a few other local speed shops said it was a waist of money. They said that they sound good but that is all and the only way that they will help is if you have forced induction. Just my thoughts and what I have been told. I was set to buy one and a mass also.

    I just dont really see how it could help on a port fuel injected vehicle. One with a carb or tbi, sure. Otherwise I think it's a waste of money. I had a 3/4 inch carbon-composite tb spacer on my supercharged grand prix but that's because the blower gets so hot and transfered heat right to it. In that case it probably helped. But mine was composite...not aluminum like just about every one of them out there. They transfer heat.

    i have one, i got it for free, so it was worth a try, it brought my truck up from 19 mpg to 23mpg, and the truck will spin the tires alot longer no into 3rd. so it was worth it if i had to pay for it
