I just installed this kit and there's a definite improvement. The throttle response was noticably quicker and the Jeep pulls through 1st & 2nd harder than before. Additionally, whereas my 6th gear was all but unusable beforethe installation (haven't regeared yet), I can now hold 6th gear on the highway without having to bury the skinny pedal.
After the installation I did a 2-mile test run around the neighborhood and as noted in the installation instructions the idle was somewhat high (1400 RPMs). But after a couple miles and stopping and restarting it adjusted back to normal.
I then let the Jeep sit for about an hour while I went out for lunch with the wife, and when I got back it wouldn't start. After 3 attempts it finally fired but ran very rough. The check engine light came on, and the code P0107 was thrown - MAP sensor low voltage. I unplugged the Edge computer, returned to the factory wiring, and everything was fine. And then re-plugged in the Edge and started it again - everything is running great now. Did another test drive and no problems.
Any idea why it threw the code? Possibly a loose plug on the computer?

In regards to the whistling sound, I purchased mine this year and it still makes that awful noise when i start it up, but once it warms it goes away and don't hear anymore. imho it is well worth the money as I now have more power and response for around town and highway driving with my 35's and slightly better mpg as well. Good initial write-up this is what swayed me to make the purchase and I too ordered mine from Thoroughbred Diesel.
I also obtained a noticable throttle response with this kit. However, the throttle is a little to "goosy" for rock crawling. I find myself having to feather the throttle when going over obstacles. Sometimes this causes me to lurch forward, which is not always a good thing. Anyone know if there is a way to tune down the module when I need to?
I just installed this kit today. Was very easy to install, just time consuming if you want perfect. After installing it wouldnt start unless i hit the throttle, but after the 6th time and holding the gas for moments it started to idle at 700 but a little jumpy. I noticed a huge gain in throttle response, in the first few gears its real jumpy a little too jumpy. I forgot to reset the battery, and my check engine light came on, so im assuming ill do that tomorrow and fix a few things. I got the Module, CAI, and Throttle Body definitely worth the money.
can anyone put up a video on youtube or something of the "whistle" this product makes?? i just want to know how loud it is. personally it wouldnt bother me, i would like to order this eventually just wondering how loud it actually is.
