Boosted Tech

If you have purchased a Supercharger for your TJ/LJ 4.0 from Boosted Tech in the last 6 months can you please answer the following questions? Thank you

How long did it Take for you to get the finished product?

What Spark Plugs did you use?

What Injectors did you use?

Are you happy with the Gains?

How Many MPG did you loose?

Did you have to make a lot of adjustments to the Tuning?

Have you already placed an order with them? I had considered installing one based on some reviews but held off for several reasons.

2005 Rubicon Unlimited, 4" Clayton long arm
35" Mickey Thompsons, lots of stuff
Black Magic Big brake kit

Yes I have placed an order with them and will provide feedback once it is installed. What I can say is that Mark has beed very helpfull answering questions. From what I can tell these kits are made to order and the lead time will vary based on how many are before you.

Don't forget the Banks Turbo is about the same price. I've yet to see any good information as to which is the better kit.

Drove one with the Banks kit and I did not like the performance. Plus its is a Turbo, I prefer Superchargers.

What about the performance did you not like? Lag?

If I had to do it all over again I would go with the super charger...only because of my 42RLE auto with proper 4.88 gearing for 32" tires. There is still a lot of "lugging/boosting" going on when in OD. On the other hand with OD off I can pull mountain grades with ease with the Banks kit. There is no turbo lag.

It just did not feel consistent. When I drove a Supercharged 4.0L it felt for consistent.

I have a supercharger, but it's not a Boosted Tech kit. I can tell you I LOVE it and can answer a couple of your questions:

How long did it Take for you to get the finished product? Pretty easy and straight forward to install. Could knock it out in a weekend no problem

What Spark Plugs did you use? NGKBKR7E

What Injectors did you use? Ford Cobra 39/lb

Are you happy with the Gains? Absolutely! Night and day difference!

How Many MPG did you loose? I've never tracked my MPG, but it likes the gas lol

Did you have to make a lot of adjustments to the Tuning? I didn't you the SS piggy back that Boosted Tech uses, I had FRP tune my factory PCM. Took 8 revisions to get it perfect

For those that are interested here is a an update on the Boosted Tech Supercharger review. Is has been a couple of weeks since the installation and tune has been completed. 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.

How easy was the install?

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

Thanks for the update!

Do you think it stresses the lower end of motor more?

Give yourself a break - low RPM boost is what most want from FI so it sounds like you got a great result

Auto trannies don't lug, their programming won't allow it - you got a great result

There are certain driving conditions where you feel like the 42RLE should either downshift from OD or not upshift to OD. The programming forces the transmission to OD. This "load" condition creates excessively high IATs and strain on the cooling system with a turbo. 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. If I get good results I'll make a how to modify '05-'06 shift parameters post.

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.
