Engine mods

This is kind of a random post just wondering if anyone knows any engine mods other than CAI, programmer, or exhaust for a '06 4.7L that are available that could improve performance. Thanks.

Some people might say a TBS (throttle body spacer) would help out a little. But I have also read that they really don't do much at all. I am getting one for my 3.7 L just because I like the noise it makes when you accelerate. My buddy has one on his jeep, I think it sounds like a turbo kicking in, I like it. And they only cost about 100.00$

So far on my 07 4.7, I have installed a fastman throttle body, AFE stage II intake, and an airram powerwire. Also run a superchips and a magnaflow muffler. Combined they work really well together. I didn't notice the throttle body making a difference till I got the superchips, then the intake really woke it up.

I have thought about adding a throttle body spacer... Right now I am running a hypertech max energy programmer and AFE stage II CAI... I really need to get new exhaust to open up the back end I think that will really help. My idea was to get my engine and drivetrain upgraded before I get my lift and larger tires. I def. do not claim to be an engine expert while I am mechanically inclined I have never had much experience. Would something like underdrive pulleys be beneficial or no? Any other mods out there for the 4.7?

Also what is the Airram powerram?

I honestly couldn't tell you if a pulley would work... Never messed with them. The Airram powerwire is a simple plug n play mod that fools the comp into thinking the air it's bringing in is colder than it is... It's good for 10hp according to the websites test and stuff

There's not too many other bolt on mods you can do unless you start swapping manifolds, headers, cams, etc.

Underdrive pulleys are suppose to be worth ~5-10 hp. Less load on the engine, but the accessory equipment (fan, A/C, Power Steering, Alternator) drive speeds are slower too.
