www.thefastman.com Plus there are others.
This guys a little pricey! Moes performance sells the same set-up for a better price.

To the OP, throttle body spacers are nothing more then $100 paper weights when it come to fuel injected, use your money on something worth while.

I've seen hp gains from TB spacers on carb'd and TBI vehicles on a dynojet, but it's usually a bit of a trade off (losing a little at the lower end of the rpm band...which isn't a great thing on a truck). The "swirl" ones have shown better results. I would expect very little if any gains, but small loss to idle control and off-idle power. Waste of $$ IMO.
of course it's all speculation until somebody dyno tests it.........

Wow, I'd get your $130 back, or expect a dyno graph with before and after results to find out what exactly he did performance wise to your ECM.
I had them do any updates to the computer and then I asked about programmers...he said he could adjust the program settings for whatever the aftermarket programmers could do and if he did it, it would still be covered...I said cool and then it cost me $130.00 to have him do it. Pricey! but less hoops to jump through if anything goes wrong...

just out a TBS on my truck and it doesn't whistle like everyone says is it to tight
[QUOTE=DesertHemi2500;2030873]So I know many of you have heard of these mythical devices that claim to sound killer and add power but has anyone here actually used one on a 4th Gen Hemi? I'm strapped for cash but when it comes to horsepower I can always find an excuse to shell out a few extra bucks so heres my question. Has anyone here actually used the Airaid throttle body spacer or any brand for that matter on a 4th gen Hemi and did you feel any difference? And I really don't care about gas mileage which I know they claim, I drive a truck so I don't expect to get good gas mileage..... I have heard they make a whistling sound which actually sounds pretty rad to me but does it really make a difference in power that's worth $120?
So I put it on there I couldn't get the bolts to match up again except one so no big deal what bout this sound??? Why no sound??

Youd be better to put that $120 in your gas tank. Complete and utter waste of cash that does nothing on an MPI motor. Anyone who says otherwise simply hasnt accepted they wasted their money. Dyno will prove this everytime.
He hasnt signed on in nearly 3 years, dont expect an answer.
