Brianj5600 A/F sensor should be in front of the cats. The cats purpose is to burn fuel left over after engine. Putting the sensor after the cat will read leaner than it really is.

JPPCAR My LJR is a 2006. Here is the link to my AFR. Prosport 60mm Premium EVO Wideband Digital Air Fuel Ratio Kit 238EVOAFRPK4.9-WO https://www.amazon.com/dp/B0115NYGMS..._w6iRDbPW3PGE4

Your AFR will be a little delayed if the sensor is after the cats.

WeezyBlue What year is your Jeep and what kind of AFRs are you seeing? My 05 doesn't seem to want to richen up until past 3psi and I don't like that. Need to make some adjustments

Brianj5600 I was confused by the wording. Thanks for clearing it up for me. I'm trying to figure out what path I want to take to get my Jeep over the Tennessee hills with a small trailer.

JPPCAR I am saying before the the Supercharger I would have to pull over . Now with the SC I am able to accelerate and pull away if I need to. Is not about how fast you can go, its about being able to accelerate on demand. I still don't travel above 70-75MPH on the highway with the LJ. It is capable of doing 90+

Pine_Cat Hyperbole - he's not really saying it's less powerful than stock - I can keep up without FI on factory gears and 33s

It's a banks non intercooler, CAI fed thru the hood with a vented hood. Water/meth kicks in @ 5 lbs and progressively sprays harder to 6.

In about 2 weeks (vac time from work) with the help of another forum member I'm going to modify the shift points using HP Tuners.

JPPCAR No - I did a lot of research on boosting a 4.0L motor and as long as you stay between 5-8lbs of boost the motor will be fine.

JPPCAR My shop that did the install said that it was a relatively install and the kit was very well thought out. Bending the AC tubes took some time to make sure they did not crack. We also did not care for the intake that came with the kit and designed our own.

As for the price of the kit it starts at $3295. Now if you are goin to purchase other items like an AFR (must have) and Boost (optional) gauge, HP Tuner,etc it will cost you more. I sourced my gauges from Amazon.

If you don't mind, how much do you estimate it cost you in the end?

Thanks for the update!

If I get good results I'll make a how to modify '05-'06 shift parameters post.

There is a significant performance increase in my LJR. It is very important that you are geared properly first before you do any kind of Boost upgrade to take full advantage of the gains or you are just wasting your money. When driving on the highway I am not able to accelerate and keep up with traffic instead of having to pull over because I am the cause of the backup in the left lane. I am not going to win any races but makes the Jeep way more drivable on the Hwy. The Boost is nice and gradual and you can definitely feel the JEEP start to pull when in Boost. I am getting a Maximum of 6lbs of boost. My gas milage is about the same but it really depends on how you drive. The first week you will want to have fun and keep boosting when you can because it is Fun and new.



My setup



Gears - 4.56

Actual tire size 33.4" 28psi

Transmission - 6sp

Fuel - 93

milage on 4.0 - 99,300



Was the money worth it? YES it was but it all depends on what you want.
