Everyone walking down the street and turns and looks to see what is making that god awful noise. There are definitely power gains, but with the full exhaust, the CAI, and the module hopefully I won't lose too much of my new found HP with the stock TB back on. Anyone wanna buy an Edge TB? I am not so happy with their tech support. I told them about the whistle and they knew exactly what I was talking about sent me some pics of where to Dremel it smoother but it didn't help at all and now they won't return my calls or emails and I can't get anyone on the phone, just VM. I have to give it 3 stars instead of 5 just because of the freaking noise. F*&*! It's so damn loud!

Update, I put the stock throttle body back on but left the CAI, and the Chip Module on. The inredibly loud whistling sound went away immediately. Nice and quiet now. Still can't get anyone on the phone at Edge Products. Trying to get an Advance RMA on this one, and try one more before I give up.

I already expect the answer to be no, but is there noticeably less power with the stock throttle body?...I was contemplating puttin the stock one back on too, I tried filing down the chamfered edge of the throttle body yesterday but it still whistles

the biggest thing I noticed with the Edge throttle body was the throttle response increased.

Yes the Edge throttle body is more responsive and precise to me. I think I am getting more HP from the exhaust, header, and module than the throttle body though. The spring on the Edge throttle body seems to be much stiffer/stronger? I'm not sure how much difference the 2 extra MM bore in the TB does for the performance but it sure makes a huge difference in the sound.

I finally got an Edge tech on the phone. I had to send my throttle body back to them, they are going to try and get rid of the whistle on this one or send me a new one. Ugh, probably take 3-4 weeks. Kind of annoying for an $800 dollar kit. I guess I will forgive them if the next one is quiet. We'll see.

Nice writeup but it really belongs in the Reviews forum. Due to the format of the Reviews forum, I can't simply move it there so please create a new review there so it'll not get lost as it would here in the TJ Tech forum.

My 2 cents on the larger bore throttle bodys: I had one on my 4.0L 2000 XJ and loved it for the high RPM gain. It really helped merging in traffic. It will cause less MPG if you gun it but if pretty even if you are a granny driver like me. One recommendation is to stay away from a guy that used to be on Ebay selling a red powder coated stock TB that he bored out. He powder coated the entire thing including the spring. Mine got stuck at WOT a couple of times. Not really a good scene to be in.

An update for my install.
I did alot of searching and asking questions. I finally spoke to the people at edge after waiting 23 minutes on hold. They, like alot of you, told me to relieve the ports.
Today I took the TB off and chamfered the ports. It definately helped reduce the whistle. You can still hear it, just not quite as bad. I also double check the allignment of the intake tube to the TB and also made sure my gasket was perfect with no over hang.
With all that said, it did make it tollerable. I do like the Edge product and would recommend it to anyone, but be forwarned, you are going to most likey have a whistle from it.

ditto...

Same here, have this kit installed on my '98 Cherokee. I have tried to dremel the port, but was fairly cautious as I didn't want to overdue it, but will now try to get to an approx. 1/8th" depth (on the bottom lip of the port) as others have said, to see if that gets rid of the dreaded whistling.

Great power for merging on the highways and climbing hills though. Hardly use any throttle (hence all the damn whistling)...

the factory manifold is right at 63mm. anything bigger, like the hesco 68mm TB's, you need to do some dremel work, or preferably CNC machining of the manifold.

What's with the throttle body that makes it special? Is it just the bigger bore? Cause i'd just bore the stock TB for much cheaper. On my last car when I was building the engine I had the TB bored and intake manny port matched. for 100 bucks.

Before and after.





The 100 bucks included a new bigger butterfly all new hardware and gasket.

Since you asked.....

Edge is on left, the stock is on right. The top view doesn't really look that much different (look at the port just above the butterfly valve):



Now look at the bottom. A HUGE difference between the two. The IAC chamber on the stock is much bigger than the chamber on the new Edge (and not just the opening below the butterfly valve).



You can see the little bit of dremel I did, and Edge spoke of. Maybe I didn't do enough but I wasn't really prepared to really hack up a new TB because they said so. I posted somewhere what I did and in the end it didn't make enought difference. I sent back the entire unit and went with a J&C bored out stock TB. It's better than stock but not as good as the Edge kit was. I just couldn't accept the noise nor was I willing to pay for BOTH the edge kit and the J&C TB for a complete kit. BTW, I did ask Edge for the kit MINUS the TB and they said no.

I hope this helps.
