Fixing the infamous TrailJammer whistle ***write up***

First of all this is not a complicated fix...

that said, i take no responsibility for any mistakes made following this write-up

Tools needed

-basic socket set
-ratchet
-hex keys
-flat head screwdriver
-dremel

This is what you should be looking at before you start, if your throttle body and intake doesn't look like this then STOP HERE



Start by removing the flexible tubing attached to the pvc one and the throttle body...



Next remove the throttle cables (didnt get a picture...sorry). the one closest to the TB just pops off like a ball socket, the other one gets removed by pulling it away from the direction the cable comes from.

After that disconnect all the wire harnesses (there should be three), they're your typical plastic catch automotive wire harnesses.

next just unbolt the four bolts holding the TB to the intake manifold and it should be free of the engine,

This is what you're fixing...


notice that there might be a small bevel already there, as there is with mine. (see below image)



Next disconnect the sensor that is over the slot you are about to bevel (see below image) this is to keep metal shavings out of it.
as you can see who ever installed this TB put the gasket on wrong...



Also check your main gasket while you have the TB off to make sure none of it is hanging over into your air channel, if there is some protruding off the edge trim the portion hanging over.


This is what your aiming for (or close to it) use a dremel by opening the throttle and shaving down gradually until you get desired results. sorry about the picture quality my camera wouldn't focus this close.. as you can see, I filed very close to the closure point but made special care not to cross it.



NOTE: do not pass where the line of closure is or else you will have a bad vacuum seal and it will cause you to idle funny as well as other things.

make sure all the metal shavings are out of the TB before you reinstall for obvious reasons..

-re-installation is basically the reverse of the steps above

if you have any question please feel free to post them.

Congrats on the whistle free jeep

Congrats on getting that resolved. I haven't heard back from Edge Products or the place I bought it from. The whistle is only half my problem, the other is the connectors are different on their module than in our TJ. I'm out of town so they may have shipped something, I'll find out tomorrow.

Does this kit really adds some power? Is it worth the price?

What attachment did you use to grind the TB with?

I think I will probably have to do this. I haven't installed mine yet.

just a basic sand paper tip..make sure to choose one gritty enough to remove metal but fine enough do do it slowly so you wont take to much off... it doesnt take much pressure to shave it down

baotchi to answer your question in the simplest terms the intake itself does nothing..its the performance module that gives you all the power...mine got stolen right out of my engine bay

I was never able to get the module to plug in, useless tech support at Edge but the TB and Intake gave a pretty healthy boost but the noise was just unbearable so I sent it back. Maybe someday they will make a module that fits my car and then I'll try it again. Just make sure you buy it from a local store that you can easily return it to.

keep in mind though, there is no difference between the TB edge sells and any other bored out TB except maybe the whistling sound and the customer service lol

Haha, actually there is a difference, the Edge (also Rubicon Express) TB's are 62mm, the bored out factory units are 60mm. Don't know how much of a difference it makes though. They finally emailed me telling me to call them, haha, they don't return calls either, what's the point. I found this article that's interesting about different mods they tried on a 4.0 Cherokee and what worked, what didn't. The CAI and exhaust had the best review, the Hypertech had the worst, the TB was good sometimes, at least the way I read it.

Personally, I like the whistle. But maybe that's just me!
