So trailfirst, you have a 2014, the PCM is unlocked.........
HP Tuners MPVI2 is 300 + 2 credits so $400

So for $400 more than a PC you get a complete tuning platform and if all you wanted was electronic throttle control, I could provide that information for free. Should you want a custom tune then that would be around $250.......so as you can see since you have a 2014 and an unlocked PCM a pedal commander is a huge waste of money and not worth it at all. I've posted this information over and over.......
Oh I don't dispute that proper tune is the go - I was tuning my 1996 Aussie I6 Falcon EECV with Tunerpro R/T before we bought the Cherokee (car dealer was convinced it was V8 when he drove it - I had to show him the engine to prove it was a six) - and I'm VERY close to pulling the trigger on a full tune setup - so might well be knocking on ur PM soon :) - BUT - the tune would need to offer same accelerator signal conditioning that the Sprint Booster achieves - else I'd just run both. Even with a proper tuner unless it can deliver the same result then Sprint Booster on top would still be good value for me. My cost on SB was close to AUD $400 (thanks to socialist govt deregulating our dollar in the 80's and conservative govts since not having balls to fix it) - but it's prolly under USD $300. Similarly I've just been running figures and the full tuner option is looking like closer to AUD $2000. I'd be VERY interested in simply purchasing a replacement or ideally exchange complete ECU with the tune in it...

Also, looking at the exhaust on our TH, it really looks to me like the otherwise really good 2.5 inch pipework pinches in to prolly 2 1/4 at the resonator inlet and outlet!? - what aare ur thoughts on that?

Don't even waste time on the exhaust it flows just fine, even with bolt on mods. You can't replace the most restrictive part on the cherokee 3.2 anyways.




Change out the muffler to something of your choice and save your money for other mods

Oh crap! - I hadn't seen that!! - so yeah point taken. On the 4.0I Falcon at one point I had extractors going into single 3 inch system - which went really well but was a bit loud (main muff was a straight thru perforated pipe design so even with front and rear resonators it was LOUD) - so after 6 months I did go back to the 2.5 inch with Aerochamber main and front and rear straight thru + chamber resonators - which sounded gorgeous - but I DID get a noticeable loss in power. I was about to put a 3 inch Aerochamber on the other system and refit it when we got the cherokee.

So yeah ok, on the cherokee if I do anything it'll be to fit an Aerochamber muff on the rear.

Not really, other than the AFE CAI,

There is a lightweight pulley but the amount of work involved to swap it out for the gains really isn't worth it at all. The 2.4 is not the best platform for any mods sadly.

What were you expecting when you purchased a 4200 lb SUV with a naturally aspirated 2.4 liter for an engine???🤔

this is my 1st time I ever had a jeep so I really didn't know too much it was a buy that I had no other choice for mine. I'm ok with the car its a really nice car but when I drive it is not like my other suvs like my Trailblazer or Envoy.

The old 4.2 I6 was a great powerful, and reliable engine. Unfortunately it has also gone away. Comparing that engine to the 2.4 Tigershark, is not even close to a good comparison. It's almost twice the displacement, and it's a 6cyl, but definitely one of the best GM engines, my Dad put 260,000 miles on his 03 Trail Blazer, and the thing still ran beautifully when he finally got rid of it. Unfortunately, those days are now gone...😎

any Jeep KL mods for 2.4L is really slow on take-offs I mean I'm not into speeding but old ladies are flying off the line way before me lololol
Engine choice has been a challenge for many, don’t feel alone. Some feel that the 2.4 is plenty for them and love it. Others not so much. No common mods will make a real difference you can feel. I suppose really lightweight wheels and tires would help the OP the most, they’re easy to change but are spendy and not offroad-friendly.

Or you can add full bolt ons and a custom tune for about 50hp.....
AFE Air intake
MMX Ported Throttlbody
Pentastar Upgrade Engine lower intake manifold
Custom engine and transmission tune.
Those above mods are good for 50hp and proven



Things to note:
Pedal commander is expensive and doesn't make the vehicle faster.
There is zero performance to gain with exhaust work as the greatest restriction is forward of the resonator and can't be replaced
A Cherokee with no mods other than a custom engine tune is still faster than a Cherokee with all the bolt on mods listed above.
Which AFE air intake? I noticed they have two different models…

Momentum Stage 2 and Momentum ST

ST doesn't flow as much but is enclosed......if you are worried about water (but don't be i've never had an issue)

Stage 2 is the one to get with the oiled filter for max air flow

thanks Tyler. I always thought oiled filters make some air fuel sensor thing dirty / throw CEL? At least that’s what I always remember with other cars…. Is oiled 100% safe for this car?

Also, not to be too off topic but, which shocks are the best for replacement for keeping the stock TH ride height in terms of performance?

and how do aftermarket suspension parts like ones made by Mevotech or Moog compare to the OEM/Mopar?

lastly, where do I get a tune and how much $?

Bilstein B6 would be a great replacement for a TH, I ran them on my TH.

As for the oil, there is no MAF sensor on these vehicles (speed density system) so no need to worry, and unless you are totally soaking the filter in oil, zero issues running

I am looking for more performance parts for my 2015 cherokee latitude 3.2l v6. It just passed 61000 miles.

I already have a K&N cold air intake, and I'm going to clean the MAF sensor.

I am about to order a new PCV valve and E3 spark plugs (shoot me for not using the oem lol). Any recommendations on performance parts and brakes and such?
I’m running a after market Gibson exhaust! Sounds good , looks good and it gives me more clearance or it doesn’t hang as low. Brakes ? If you find brake upgrades let us know.Happy Jeeping 😃

I have dobinsons shocks all around awesome set up, but you can’t go wrong with bilstein6s . 1000$ for dobinsons +450$ install, worth it so far.Happy Jeeping 😃

tyler, what about just bolt on mods, no ecu, pcm or tcm tune, like the lower intake manifold, throttle body and intake, do you have the results for just those alone? Pretty curious to see the results of a FBO cherokee without tunes, There is probably a thread for this, so sorry in advance but id rather do FBO at the moment before i tune it
