Current engine mods in order:

Re: Ported Throttle Body installed

What kind of airflow (CFM) increase are you suppose to get with the ported Throttle Body?

sweet bro! our jeeps are very similar except your 2" lift

i also love the k+n and magnaflow, how do you feel about the power wire?
do you reset your pcm often? i find the throttle gets peppy after you reset the pcm.

I noticed a little difference in acceleration after I installed the powerwire, although its mainly noticeable at WOT. I think the main mods to make the most notable difference is the air intake,muffler and ported throttle body, It also doesn't hurt to run synthetic oil to help extend oil changes(6k instead of 3k) and to help prevent sludge build-up. Everything helps and so far I'm pleased.
How do reset the pcm? do you just unhook the battery?

Swapping the throttle body is a fairly easy mod to do on these motors
I did mine is lest than 10 minutes, but take your time if you haven't done this before.

1. take flat blade screw driver and undo clamps on air resonator, remove air resonator.
2. You should see 4 bolts holding the throttle body to the intake manifold.Unplug the drive by wire connector from the tb or disconnect the cables if you have cable driven tb.
3. get a ratchet with either 9 or 10 mm remove the four bolts and remove the tb. Installation is the reverse of removal. Make sure you get the bolts snug and that everything is reconnected properly.start it up and make sure there is no leaks or check engine light, then your good to go. I would unhook the battery for a few minutes to let the ecu reset and start fresh with the new tb.

Seems very straight forward, thanks for writeup!

BTW, I installed my K&N 57-1545 this morning. Since you have the same setup I have a quick question. How did you modify the crank case vent hose to hook up to the intake tube? If I hook it up as is, it has a kink in it. I am thinking I need to take off the flexible hose part, trim the stiffer plastic tubing, and then put the flexible hosing back on. What did you do for yours?

Thanks in advance, you've been very helpful for me!

I didn't want to cut either the oem rubber hose or the plastic part so for the vent hose I used a piece of old curved heater hose and cut it down until the angle was right and then used used two screw clamps to secure it to the plastic tube and nipple on the intake. Ill try to get a picture of it for you.

Sounds like a good solution. I actually went ahead and cut off some of the plastic tube so that the flexible tube now makes a nice soft angle to the nipple on the intake tube. I figure if I ever revert back to stock, I can just pick up a new plastic tube......cant cost too much.

Thanks for the input, and sorry, I really should have made this a separate thread. But thanks again for your replies.........I think a ported tb is in my future

Re: Ported Throttle Body installed

can someone chime in on how exactly to reset the ecu. i installed my ported tb last week and the install was super easy but something wasn't right, i had a ton of problems (long throttle delay, seemed to perform worse than stock, and the throttle would pulsate, at one point my jeep excelled on its own and luckily i had my foot on the brake). so naturally after installing it and reinstalling it to make sure everything was done correctly i took it back out and put the stock one back in, everything was back to normal...bad tb? or does the ecu need reset?
