wow I just put the AEM cold air intake and throttle body spacer on and the truck actually sounds better when you floor it. It has a much deeper grunt to it now. I have only run the tuner on 87 oct. program with new intake so far I am waiting to fill up with 93 oct. and reprogram to see difference. Their is a huge difference between 87 tuning and 93 tuning before with out the intake so hopefully their will be just as big of a difference in performance with the intake.

To anyone with an R/T with a superchips tuner I HIGHLY RECOMEND THE AEM KIT WITH COLD AIR INTAKE AND THROTTLE BODY SPACER YOU WILL BE VERY HAPPY!!!!!

let me know if any of yall need to know anything else about the truck.

That is what I thought too. I thought the spacer was just a waste of time but I was bored and had nothing better to do and installed it a couple of days after the intake. I promise it works alot better with the TB spacer. I don't know how but that little chunk of metal somehow made it run faster.

Have you tried the tb spacer on there or did you really toss it?

Not to take the wind out of your sails, the following is from V8performance.com



Throttle Body Spacers (Primarily the "Helix" style):

These spacers do not provide any gains in HP at all. They claim to increase TQ and MPG but we tested one and it gained nothing. The Dyno showed no gains in HP or TQ. We also had contacted one of the manufacturers for their comments on them and here's the direct quote (from email):

Dear Sir, thank you for your inquiry in our products. The spacer makes no HP on the Dyno. It makes all of it's power in torque in the low end. If you haven't noticed any power on the Dyno or the track then it's doing what it's supposed to. You would not see any gains down the 1/4 mile or increases on the Dyno. The idea of the spacer is to improve overall drivability and fuel mileage. In most cases when people install a bolt on part they expect better mileage and power, what happens is they are into the throttle a lot more than before trying to test performance and that's when the decrease in mileage happens.

Sincerely,

"The spacer makes no HP on the Dyno. It makes all of it's power in torque in the low end."
"If you haven't noticed any power on the Dyno or the track then it's doing what it's supposed to."
"The idea of the spacer is to improve overall drivability and fuel mileage."
So...it doesn't make any more HP, is not supposed to help in 1/4 mile performance (or on the Dyno), and is mainly for mileage and bottom end Torque. Well, Dyno's show TQ figures and there were no changes, mileage stayed the same, and 1/4 mile performance wasn't affected on the several others who have tried it (including us). They also are still not able to explain how the spacer keeps the swirl effect through the two turns (90 degree and 45 degree) in the intake plenum of the Dodge Ram/Dakota/Durango manifolds.

While the Throttle Body Spacer showed no gains on the 3.9/5.2/5.9L Magnum engines, the 4.7L engines have been reported to show noticeable gains from the spacer. Why? It's a much more efficient intake system with less restrictions than the Magnum engines. It may work just fine for the 4.7L crowd but we'll look into this at a later date for Dyno and long term MPG testing.

No I uderstand. I heard the same stuff before I installed mine thats why at first I just left it off. I don't know if the spacer did it or not but after I installed it it was running much better. Mabey I didn't have the intake all buttoned down when I installed it the first time and after I re-installed it with the spacer I put something on that I missed before.

I tend to think that I did something wrong on the first istall but I don't know what it could have been.

Anyways I have free access to a chassis dyno and will run it before and after the TB spacer to check the HP gain or lack there of.
